DVSA Road Signs and Markings 4 — Questions and Answers
Question 1: What do single white broken lines along the centre of the road mean?
- No overtaking allowed
- You may cross the line to overtake if safe (Correct answer)
- Dual carriageway ahead
- Cycle lane boundary
Correct answer: You may cross the line to overtake if safe
A single broken white centre line separates traffic flowing in opposite directions. You may cross it to overtake if the road ahead is clear and it is safe to do so.
Question 2: What does a triangular sign showing two cars side by side (one red, one black) mean?
- Two-way traffic crosses a one-way road (Correct answer)
- Road narrows on both sides
- No overtaking
- Dual carriageway ahead
Correct answer: Two-way traffic crosses a one-way road
This warning sign alerts you that two-way traffic crosses ahead or that you are about to enter a road with two-way traffic. It is commonly seen when leaving a one-way street or dual carriageway.
Question 3: What does a green rectangular road sign indicate?
- Tourist information
- Primary route direction (Correct answer)
- Motorway information
- Emergency diversion route
Correct answer: Primary route direction
Green background signs are used on primary routes (major A-roads) to show directions and distances. Motorways use blue signs, local routes use white, and tourist destinations use brown.
Question 4: What do short broken white lines across your side of the road at a junction mean?
- Stop and wait for a green light
- Give way to traffic on the major road (Correct answer)
- Mini-roundabout ahead
- Pedestrian crossing ahead
Correct answer: Give way to traffic on the major road
Broken white lines across the road at a junction are 'give way' lines. You must give way to traffic on the major road before proceeding. If the lines were solid, it would be a 'stop' line and you must stop even if the road appears clear.
Question 5: A sign showing a red circle with a motorcycle inside it means what?
- Motorcycle parking only
- Motorcycle route ahead
- No motorcycles allowed (Correct answer)
- Warning — motorcyclists ahead
Correct answer: No motorcycles allowed
A red-bordered circular sign with a motorcycle symbol prohibits motorcycles from using that road or area. Red circles always indicate a prohibition or restriction.
Question 6: What does a white arrow curving to the left on a blue circular background mean?
- Keep left — pass the obstruction on the left side (Correct answer)
- Left turn only
- One-way street to the left
- Diversion route to the left
Correct answer: Keep left — pass the obstruction on the left side
This mandatory sign instructs you to keep left and pass an obstruction or traffic island on the left side. A similar sign with a rightward arrow means keep right.
