PCV PCV Road Signs & Highway Code 4 — Questions and Answers
Question 1: What does a white circle with a black horizontal bar indicate?
- End of a speed restriction or other prohibition (Correct answer)
- No stopping at any time
- National speed limit applies
- End of a bus lane
Correct answer: End of a speed restriction or other prohibition
A white circle with a black horizontal bar through it indicates the end of a restriction (such as a speed limit zone or prohibition). After this sign, normal road rules apply for that restriction category.
Question 2: What does a yellow line running along the kerb edge mean?
- Waiting restrictions apply at certain times — check the sign nearby for the hours (Correct answer)
- No parking at any time
- No parking Monday to Saturday
- Buses only may stop here
Correct answer: Waiting restrictions apply at certain times — check the sign nearby for the hours
A single yellow line along the kerb indicates waiting restrictions during certain times shown on a nearby sign. The sign specifies days and hours. PCV drivers must check the sign to determine if waiting is currently permitted.
Question 3: What does a 'box junction' (yellow cross-hatched box) require of a bus driver?
- Do not enter the box unless the exit is clear — the exception is turning right when only prevented by oncoming traffic (Correct answer)
- Stop before the box and give way to all traffic
- Buses are exempt from box junction rules
- Only enter the box when no other traffic is waiting
Correct answer: Do not enter the box unless the exit is clear — the exception is turning right when only prevented by oncoming traffic
Box junction rules apply equally to buses. A bus must not enter a yellow box unless its exit road is clear. The right-turn exception (waiting in the box when oncoming traffic prevents the turn) applies to buses as well.
Question 4: What does a white circular sign with '30' in a red border indicate?
- Mandatory 30 mph speed limit for all vehicles including buses (Correct answer)
- Advisory 30 mph for heavy vehicles
- 30 mph minimum speed
- Temporary speed limit during roadworks
Correct answer: Mandatory 30 mph speed limit for all vehicles including buses
A red-bordered circular sign showing a number indicates a mandatory maximum speed limit. All vehicles, including buses and coaches, must not exceed 30 mph where this sign is displayed.
Question 5: What does a sign showing a bus and a bicycle on a blue background together mean?
- A lane or road shared by buses and cyclists — other vehicles not permitted (Correct answer)
- Buses must give way to cyclists
- Cyclists must use buses for this route
- Buses and cycles have the same speed limit here
Correct answer: A lane or road shared by buses and cyclists — other vehicles not permitted
A blue sign showing a bus and bicycle together indicates a lane or road shared by buses and cyclists. Other vehicles are excluded. PCV drivers must be especially aware of cyclists in these shared spaces.
Question 6: What does a red triangular sign with a bicycle symbol mean?
- Cyclists ahead — be prepared to slow and give way (Correct answer)
- A cycle route crossing the road
- Cyclists must dismount
- No cycling in the area ahead
Correct answer: Cyclists ahead — be prepared to slow and give way
A red warning triangle with a cycle symbol warns of cyclists likely to be ahead, on or crossing the road. PCV drivers should reduce speed and watch carefully for cyclists, especially at junctions.
