This guide explains the most important Dutch theory points about traffic signs and road markings: how signs and markings work together, how to read shark teeth, bike boxes, hatched areas, lane arrows, and the common exam traps that appear in Category B theory questions.
Why this topic matters
Traffic-sign and road-marking questions often look simple, but they are usually mixed with priority, lane choice, speed, or roadworks. Many learners lose points because they focus on only one clue, while the real answer depends on how signs, markings, and the road layout work together.
Key rules in 60 seconds
Signs come first
- Mandatory traffic signs and lane signals must be followed.
- Road markings help guide traffic, but they do not replace the meaning of a traffic sign.
- Always check the sign first, then confirm it with the road layout and markings.
Recommended speed
- A recommended speed is advisory, not a legal maximum.
- It is used where a higher speed could be risky, for example at a sharp bend or exit.
- In poor weather, you may need to drive even slower than the advisory speed.
Shark teeth and lane markings
- Shark teeth mean you must give way.
- Lane arrows show where your lane is meant to go.
- If arrows and solid lines commit you to a lane, do not make a late lane change.
Markings you must recognise quickly
- Bike box: reserved space for cyclists at traffic lights.
- Hatched or gore area: not for normal driving.
- Temporary yellow markings: follow them during roadworks.
What the exam asks most often
- What do shark teeth mean?
- What is the difference between a mandatory speed sign and an advisory speed sign?
- May you drive on a hatched or gore area?
- What is a bike box used for?
- Which markings matter most during roadworks?
Detailed guide
Signs and markings work together
In Dutch theory, the safest way to read the road is to start with the traffic sign, then check the markings and lane layout. Signs often give the legal instruction, while markings help show how to position the vehicle correctly.
Maximum speed and advisory speed
Learners often confuse a legal speed limit with an advisory speed. A speed-limit sign creates a legal maximum. An advisory speed sign is a warning-style recommendation used where a higher speed could be unsafe.
- Always follow the legal speed shown by the applicable sign or lane signal.
- Use the advisory speed as a practical safety guide.
- In poor visibility or low grip, the safe speed may be lower than both.
How signs usually apply
Many signs apply from the point where they are placed and continue until another sign changes the situation, or until the road layout clearly changes the traffic situation. In theory questions, always watch for repeated signs, side roads, zone signs, and supplementary plates.
Shark teeth
Shark teeth are one of the most common exam clues. They mean that the drivers facing the shark teeth must give way to the traffic on the crossing road.
- Do not treat shark teeth meant for crossing traffic as steering guidance for your own turn.
- Combine shark teeth with cyclists, turning traffic, and the full junction layout before answering.
Bike box
A bike box is the reserved waiting space for cyclists in front of motor traffic at a traffic light. It improves visibility and helps reduce blind-spot conflicts.
- Do not stop inside the bike box.
- Keep it clear for cyclists and low-speed mopeds where applicable.
- When the light changes, expect cyclists to move off first.
Hatched areas and gore areas
Hatched areas, divider markings, and gore areas are not there as extra driving space. They are used to separate traffic flows, protect space, or guide traffic into the correct lane early.
- Do not drive on them in normal situations.
- Choose the correct lane early instead of crossing them at the last moment.
- Late corrections across marked separation areas are a classic theory mistake.
Temporary yellow markings
During roadworks, temporary yellow markings and temporary traffic signs are the markings you should follow. They can change the normal lane layout or route through the work zone.
- Do not keep following the old white markings if the temporary yellow layout shows something else.
- Reduce speed and read the road earlier than usual in work zones.
Yellow broken line
A yellow broken line is another marking that often appears in mixed exam questions. It means no parking on that side of the road, but a short stop for immediate passenger movement or loading and unloading is still allowed.
Common mistakes to avoid
- Using road markings alone and missing the traffic sign.
- Treating an advisory speed as if it were a legal maximum sign.
- Driving on a hatched or gore area to save time or fix a late lane choice.
- Stopping in a bike box at traffic lights.
- Ignoring temporary yellow markings during roadworks.
Quick FAQ

A reserved waiting area for cyclists in front of motor traffic at traffic lights.
Not in normal driving. These areas are meant to separate or guide traffic.
It is a recommended speed, not a mandatory maximum speed.

Relevant Dutch rules and exam context
- RVV 1990, Art. 62–63: mandatory traffic signs and signals must be obeyed.
- RVV 1990, Art. 81: shark teeth mean drivers must give way to traffic on the crossing road.
- CBR exam guidance: shark teeth for crossing traffic are not lane guidance for your own turning line.
- CBR / Dutch road-marking rules: hatched and divider areas are for traffic separation and should not be used as normal driving space.
