Prohibitory Signs

The essentials

Prohibitory signs introduce or cancel specific traffic prohibitions and restrictions. This topic teaches whom each restriction applies to, where it begins and under what conditions it may end or not apply.

What to remember

Prohibitory signs introduce or cancel a specific restriction—entry, movement of certain vehicle types, speed, overtaking, stopping or parking, and so on. Always check where the sign’s effect begins and ends, which side of the road it applies to, what exceptions exist, and whether a supplementary plate limits the time, direction or vehicle category.

A small practice set from this subtopic. The full question bank and saved progress are available in your account.

The drivers of which vehicles violated the requirements of the road sign? The drivers of which vehicles violated the requirements of the road sign?
  1. Motorcycle drivers
  2. Drivers of a car and a motorcycle with a side trailer
  3. Car driver only
  4. Drivers of all vehicles

The correct answer: Drivers of all vehicles

The correct answer is that all drivers violated the sign. The circular prohibition sign bars motor vehicles from continuing in that direction. It applies to the car, the ordinary motorcycle, and the motorcycle with a sidecar, so none of the three vehicles shown should have proceeded beyond the sign.

Does a prohibitory sign affect the part of the road where the driver has stopped? Does a prohibitory sign affect the part of the road where the driver has stopped?
  1. It affects.
  2. It does not affect.

The correct answer: It affects.

The correct answer is “It affects.”. Combine the sign, marking, required distances and remaining road width, while distinguishing stopping from parking. Remember: check the sign, then the distance and free space, and distinguish stopping from parking. In the other choices, the vehicle position or distance fails at least one stopping or parking condition for that location. Only the correct option satisfies the full set of requirements.
