The foundation of learning road signs is knowing their groups, distinguishing features, and how signs in a given group should be interpreted. This makes it easy to avoid mistakes, such as confusing the mandatory sign indicating driving straight ahead with the sign informing about a one-way road. Both are blue signs with a similar white arrow, but one is circular (indicating an obligation), while the other is square (informational).

Formally, there are 10 groups of signs, but in the case of road signs, four main groups are most commonly described: Warning, Mandatory, Prohibitory, and Informational.

Besides these, there are other “post-mounted” signs, such as plates, supplementary signs, town signs, as well as signs painted on the ground and traffic lights.

Why Is It Worth Knowing Different Character Groups?

Knowing the main groups allows you to create your own connections between road signs based on their visual similarity or function. These mini-groups are created for personal use; for example, you can group signs according to turns and arrows, which significantly speeds up learning. You can then create a group of signs relating to one-way roads and “add” signs from various main groups to it.

General rules related to learning road signs.

Learning road signs should not consist solely of memorizing their names. More important is understanding how to behave after seeing a given sign: what you may do, what you must not do, and what you need to watch out for. A sign always refers to a specific situation on the road and often works together with other signs, traffic signals, or road markings.

At the beginning, it is worth taking a few quick tests to become familiar with the way questions are asked, but you should not base all your learning on them. First, it is a good idea to learn the general rules of the road, and only then return to the tests and analyze your mistakes. This way, the tests become a tool for reinforcing knowledge rather than randomly clicking answers.

Main groups of characters

Legal classification of road signs.

We have 10 main groups:

Warning signs, A
Road markings, P
Prohibition signs, B
Mandatory signs, C
Information signs, D
Additional signs, G
Supplementary signs, F
Direction and locality signs, E
Traffic lights, S
Plates accompanying signs, T

This should be supplemented by instructions given by traffic controllers (primarily police officers), which take precedence over all other signs. Traffic lights come second and take precedence over the remaining signs. At the very end are the general rules of the road, e.g. that the vehicle on the right has the right of way.

There are also Road Traffic Safety Devices. They are not road signs in the legal sense, they look similar, and they serve similar functions.

A Practical Classification of Road Signs in Poland. A Mind Map of Road Signs.

For convenience, signs can be grouped into larger sets. The main classification divides all signs into:

Typical signs “on a post”
Other forms of signs (lights, road markings painted on the ground, etc.)
Instructions from persons directing traffic.

UBR-type objects, which we are skipping for now.

Typical signs can be divided into:

The Big Four (UN + I) (or (ABCD), namely: Warning, Mandatory, Prohibitory and Informational signs
Other post-mounted signs: supplementary plates for signs, supplementary signs, direction and locality signs.

This division has no legal basis; I created it to make learning easier, and it is possible that other groupings would make more sense. For example, some information signs could be moved to the “other” group. Many information signs directly concern the rules of the road, such as those indicating right of way or parking areas. The functions of other signs have been superseded by the Internet, as is the case, for example, with signs indicating a hotel, restaurant, campground, etc.

Information Sign D-1 – Priority road; you have priority over vehicles at the intersection. You must still watch out for pedestrians at the crossing, traffic lights, emergency vehicles, and a police officer’s instructions.

The Big Four (UN+I) or ABCD

Among the signs on the post, it is worth distinguishing four main groups to learn first: warning, mandatory, prohibitory, and information signs. They can be remembered as ONZ + I. This division does not result from any relevant legal provisions; it simply speeds up learning by focusing on them.

This division works well because these four groups most often immediately answer the question: what should I do on the road? Some warn, others prohibit something, others require a specific way of driving, while still others provide information about the rules in force in a given place.

The UN numbering is obvious, but it is informal; in the legal system, signs from this group are marked with the letters A, B, C, or D. Formal legal numbering is not essential in practice, but it is worth knowing how it works when looking for a specific sign.

O: Warning Signs, Formally (A)

Warning signs are designated by the letter A. They are usually triangular, with a yellow background, a red border, and a black symbol. In this case, there are no exceptions (with other groups of signs, this is not so obvious). The purpose of warning signs is simple: they are intended to alert the driver that they are approaching a place where a hazard may occur.

They may warn of a bend, intersection, pedestrian crossing, children, roadworks, a slippery surface, a road narrowing, or a railway crossing. In themselves, they do not always prohibit a specific maneuver, but they require the driver to exercise greater caution.

A-5 Intersection where priority is not indicated by signs (i.e. an equal-priority intersection)

Simply put: A signs say “be careful, it may become dangerous shortly.” Sometimes this only means taking your foot off the accelerator and observing the road more carefully, while at other times it means preparing to brake. A special case is A-7 “give way,” because in addition to providing a warning, it imposes a specific obligation to yield the right of way.

A-7 – yield right of way

Warning signs are quite intuitive; these two signs, namely “intersection without signs” and “give way,” are probably the only signs that need to be memorized.

The remaining signs are simple and intuitive enough that once you learn them, you can easily deduce their meaning. It is also easy to create subgroups, such as bends, intersections with a minor road, etc.

The phrase Warning Signs can help with remembering the letters.

N: mandatory signs, (C)

Mandatory signs are designated by the letter C. They are usually circular, blue, and feature a white symbol. In fact, there are no exceptions.

Their meaning is more imperative than that of warning signs, as they tell the driver what to do.

This group includes, among others: mandatory straight-ahead direction, mandatory right turn, passing on the right side of the sign, roundabout, cycle path, pedestrian path, or pedestrian and cycle path.

Simply put: C signs tell you “you must drive or behave in this way.” If you see a sign requiring you to drive straight ahead, you must not turn. If a sign instructs you to pass an island on the right, you pass it on that side. If you see a cycle path, cyclists should generally use it, provided it leads in their direction.

The phrase NakazywaĆ may help with remembering the letters.

Z: Prohibition Signs (B)

Prohibition signs are usually circular and consist of a black symbol (or a black and red symbol, sometimes with orange elements), a white background, and a red border. Although there are exceptions, it is still obvious that they indicate a prohibition. The end of a prohibition is not intuitive; it simply has to be memorized.

This is one of the most important groups in terms of fines, penalty points, and liability for a collision.

Prohibition signs indicate what is not allowed. They may prohibit entry, movement, turning, making a U-turn, overtaking, stopping, parking, or exceeding a specified speed.

Simply put: B signs say “you must not do this.” If there is a no-entry sign, you must not enter. If left turns are prohibited, you must not turn left. If the speed limit is 40 km/h, you must not drive faster just because the road looks empty.

Prohibition signs often apply from the point where they are placed up to the nearest intersection or a sign cancelling them, but this is not an absolute rule for every sign. Always pay attention to the specific sign and any supplementary plate beneath it.

B-3 No entry for motor vehicles, except two-wheeled motorcycles

B-35 No stopping sign

Unlike warning signs, more signs in this group are less intuitive, so this group requires more attention, especially since violating a prohibition has more serious consequences than failing to exercise sufficient caution.

The phrase ZaBrania się can help with remembering the letters.

I: information signs, i.e. (D)

Information signs are designated by the letter D. Their name can be somewhat misleading, because “informational” does not mean “unimportant.” Many D signs actually change the rules of traffic. Informational signs can be divided into two subgroups: important signs that indicate legal rules, and tourist signs. Tourist signs are, in fact, of little importance. Some informational signs protect us from wasting time (entering a road with no through passage means having to turn back; ignoring such a sign does not expose us to a fine, provided that we do turn back). Some informational signs are relics of the past, remnants of the pre-smartphone era.

The hotel or post office sign was useful when using a paper map or not having a map at all. Perhaps some people still use these signs; they may potentially be useful during crises, but generally they do not appear in either the theory or practical driving licence exams).

Sign D-25, indicating a public telephone at a post office, is simply obsolete, and there is no need to know it.

Some of these signs are completely outdated, such as the sign for a post office with a publicly accessible telephone. Post offices no longer offer such a service; almost everyone who owns a car also has a phone, and publicly accessible telephones are currently found only in hospitals and prisons.

Sign D-4b: the road beyond the intersection, in this case on the right, is a dead-end road.

Important information signs include, for example: priority road, end of priority road, one-way road, pedestrian crossing, parking, bus stop, residential area, built-up area, internal road, and motorway.

Simply put: D signs indicate “this is the applicable traffic organization here.” Sign D-1 informs you that you are on a priority road. D-3 indicates that the road is one-way. D-6 marks a pedestrian crossing. D-40 introduces a residential zone, where pedestrians have strong priority and drivers must proceed with particular caution.

Information signs should not be treated as ordinary hints. They are often the ones that indicate which traffic “mode” applies in a given place.

Generally, information signs are blue rectangles with white symbols, or with a white rectangle inside and black symbols. Although there are a few exceptions, these two are the least intuitive:

Besides these, there are a few other informational signs that do not use a blue background, but in these cases it is obvious that they are informational signs.

The phrase Informacje Dobre may help with remembering the letters.

UN Summary + I (ABCD)

Warning A: be careful, danger is approaching. Mandatory C: you must behave in a specific way. Prohibition B: you must not perform a given maneuver or action. Information D: a specific traffic arrangement or important rule applies here.

This division is a good starting point because it immediately teaches practical thinking. Instead of memorizing a sign as a picture, you ask yourself: is it warning me, prohibiting something, requiring something, or informing me about the rules in this

Other bar marks. (TEF)

Besides the Big Four, namely signs A, B, C, and D, there are also other groups of signs and markings. They are usually not the first stage of learning, but they are still very important. They often do not explicitly say “you must not” or “you must,” but instead help you understand traffic organization, the direction of travel, exceptions, or special situations.

T: supplementary plates for signs

T plates are placed beneath road signs and clarify their meaning. This is a very important group, because a supplementary plate is neither decoration nor loose information. It must be read together with the main sign.

T-4: sign indicating the number of bends

The supplementary plate may indicate which section the sign applies to, the distance from which it takes effect, the hours during which it applies, which vehicles it concerns, or whom the prohibition does not apply to. It may also show the route of the priority road at an intersection.

Example: the no stopping sign by itself means something different from the same sign with an additional plate stating that it applies only during specified hours. Similarly, a sign with a plate saying “except bicycles” must be understood differently from a sign without that plate.

T-6a: actual route of the priority road through the intersection

Road sign plates come in many shapes and colors, so there is no point in memorizing the main design principles; it is enough to remember that they appear beneath the main sign as a supplement.

Simply put: T says “read the sign more carefully, because there is a condition or exception here.”

E: Direction and locality signs

E signs help drivers find their way. They include various types of directional signs, town-name signs, information about road numbers, directions to the city center, districts, motorways, expressways, etc.

Their main role is navigational. They usually do not speak as directly as a prohibition or mandatory sign—“you must not” or “you must.” Instead, they help you decide in advance which lane to take and in which direction to drive.

This does not mean, however, that they are unimportant. At larger intersections, roundabouts, and on expressways, E signs are crucial because they allow drivers to prepare for a maneuver in advance. Thanks to them, drivers do not have to change lanes abruptly at the last moment.

Simply put: E tells you “this is the way to go in a given direction.”

F: supplementary signs

F signs supplement information about traffic organization. They often show lane layouts, detours, changes in traffic organization, how to pass through an intersection, the end of a lane, lanes for specific vehicles, or directions for individual lanes.

This is a group that is particularly important in the city, during roadworks and at more complicated intersections. An F sign often does not prohibit something as explicitly as a B sign, nor require something as directly as a C sign, but it helps you understand what is about to happen on the road.

Example: a supplementary sign can indicate in advance that the right lane is for turning only, the left lane continues straight ahead, and the middle lane ends. If a driver ignores such a sign, they may later make a hasty or dangerous maneuver.

Simply put: F says, “Look at how the road ahead of you is organized.”

F-7: driving procedure in connection with the prohibition of turning left

Summary of T, E and F

The T, E, and F signs can be regarded as the second group of bar signs after the Big Four.

T clarifies the main sign. E leads to directions and localities. F explains the traffic organization.

They are not formally “inferior” to signs A, B, C, and D. They simply serve a different function. The Big Four most often tell the driver directly what to do, while T, E, and F help explain the details: where to drive, how the road runs, whom the sign applies to, and what the exceptions are.

Unusual signs, not post-mounted.

In addition to the typically “post-mounted” signs, such as A, B, C, D, E, F, and T, it is worth distinguishing separately the signs and signals that look somewhat different, although they function similarly to the typical signs—in fact, they are closer to the signs from the “big four” than to supplementary signs.

They do not look like a classic sign face by the roadside. This refers to traffic lights, markings painted on the ground, and (less frequently) posts (sign faces) and crosses.

These are still important elements of traffic organization. The difference is that we do not learn them merely as a “sign on a post,” but as a separate form of road communication.

Traffic Lights, or S

Traffic lights are signs and signals displayed using lights. We most commonly associate them with three colors: red, yellow, and green, but there are also directional signals for pedestrians, cyclists, trams, buses, and railway crossings.

Legally, traffic lights are very important because they take precedence over signs regulating right of way. If traffic lights are operating at an intersection, you do not determine right of way solely on the basis of D-1, A-7, or B-20 signs. You follow the lights.

four-phase traffic light system

The simplest way:

red: stop, you must not drive or enter, yellow: prepare to stop; do not proceed if you can brake safely, green: you may drive or walk, but you must still be careful.

It is also important to remember that a green light does not mean “I can do anything.” You must not enter an intersection if there is no room to continue driving. You must also watch out for pedestrians, cyclists, emergency vehicles and the road situation.

Road Markings, or P

Horizontal road markings are markings painted on the road surface. They include solid lines, broken lines, directional arrows, pedestrian crossings, cycle crossings, stop lines, areas excluded from traffic, BUS inscriptions, and bicycle symbols.

These are not “less important signs,” but a normal part of road markings. A solid line may prohibit crossing it, an arrow on the lane indicates the permitted direction of travel, a zebra crossing marks a pedestrian crossing, and a stop line indicates where you must stop.

Simply put: P signs tell the driver how to move along the roadway itself. They indicate lanes, directions, stopping places, crossings, level crossings, and boundaries that should not be crossed.

Road markings are particularly important at larger intersections. You may have a green light, but if the arrow on the lane allows only a right turn, you cannot go straight from that lane.

Additional signs before railway crossings, i.e. G

G signs are additional signs associated with railway crossings. They are not as “typical” as prohibition or mandatory signs, as they often take the form of indicator posts or St. Andrew’s crosses.

Their purpose is to warn the driver that they are approaching a railway crossing. This is a particularly dangerous place because a train cannot stop as quickly as a car. Therefore, the driver should slow down in advance, observe the tracks, and make sure it is safe to cross.

Road sign G-1a: Delineator post with three stripes placed on the right side of the roadway

This group includes, among others:

marker posts before the crossing, indicating that you are approaching the tracks,
St. Andrew’s cross, which marks the location of the railway crossing,
signs indicating whether the crossing has one or multiple tracks.

G-3 St. Andrew’s Cross

It is important to distinguish between them: the crosses and posts before a level crossing are signs from group G, but the barriers, half-barriers, and other barriers themselves are more properly level-crossing protection devices rather than ordinary road signs.

Instructions from a Police Officer and Other Persons Directing Traffic

There are also “signs” on the road that are not mounted on posts or painted on the roadway. These are the instructions and signals given by a person directing traffic. This may be a police officer, but also, for example, a firefighter during an operation, a person directing traffic at roadworks, a railway employee at a level crossing, or someone escorting children across the road.

This is the most important level in the entire hierarchy. If traffic is being directed by an authorized person, their instructions take precedence over traffic lights and road signs. In other words, if a police officer signals you to stop, you must stop even when the light is green. If the officer signals you to go, you follow the instruction provided you can do so safely. This follows from Article 5 of the Road Traffic Act.

The basic gestures can be remembered most simply as follows: if the police officer is standing sideways to your direction of travel, it means you may proceed. This works similarly to a green light. If you see the front or back of the police officer, you must stop. This works like a red light. When the police officer raises an arm, it indicates a change of signal, similar to a yellow light: those who were moving should prepare to stop, while those who were stationary should not set off yet, but wait for the next signal.

A traffic controller may also give a specific driver an instruction—for example, indicating with a hand, paddle, flashlight, or whistle that they should stop, move forward, or proceed. A whistle alone does not replace the gesture. It is most often used to attract attention so that the driver looks at the traffic controller and understands their instruction.

It is therefore worth adding a separate category to the learning material: human signals, meaning the instructions of people directing traffic. These are not road signs in the classic sense, but in practice they are more important than all signs on posts, traffic lights, and road markings. In short: a person directing traffic takes precedence over traffic lights and signs.

Grouping characters in practice.

Frequently confused signs are C-5 (mandatory direction straight ahead) and D-3 (Information about a one-way road). These signs are very similar, but if you remember that blue circular signs indicate mandatory directions, while information signs are squares/rectangles, it is easy to understand that the first sign prohibits turning right/left and making a U-turn, whereas the information sign indicates that the road is one-way (meaning that at the nearest intersection, you may turn).

U-turns are also prohibited on a one-way street (because we would be driving against the flow of traffic). No U-turn sign

One-way traffic can also be achieved using sign B-1 – No entry.

Road Sign Learning Plan.

Simply memorizing the names of signs makes no sense; what matters is knowing how to behave when you see a sign—what you can and cannot do. A sign does not exist in a vacuum; it relates to the road, intersection, or bend, and works together with other signs.

At the very beginning, it is therefore worth doing a few quick theory tests, thanks to which you will intuitively learn the general principle of thinking through and answering test questions. This should not be the basis of your learning, so it is best to spend about 20 minutes on it, or an hour at most.

TestsPrawko.pl

The next stage is learning the general rules of the road. This information is most often provided by a driving school in the form of lectures or self-study materials. You can also use other resources available online, YouTube videos, or textbooks.

The basis is, of course, the law; however, learning the rules of the road from legal provisions is not particularly effective. It is nevertheless worth knowing the basics of the law, so that in complex matters you can refer directly to the relevant provisions—for example, when two articles on the Internet present contradictory claims. One of the key things at this stage is to understand how road signs work in general.

With this knowledge in mind, it is worth returning to completing tests and analyzing the answers to make sure that you are certain about each question. Thus, after the learning phase, we enter a stage of alternating between completing tests and continuing with “typical” learning. It is at this stage that the need arises to memorize at least some of the signs.
