Question

Difficulty: MediumRoundabouts

As you arrive at a roundabout, you observe that traffic on the circulatory carriageway is moving slowly and the entrance ahead is partially blocked by a queue. What action should you take before crossing the give way line?

  1. A
    Drive onto the roundabout immediately and queue closely behind the preceding car to protect your entry space
  2. Hold back behind the give way line until sufficient space clears so that you do not obstruct other road usersAnswer
  3. C
    Flash your headlights repeatedly to signal the queuing drivers on the roundabout to move forward
  4. D
    Move rapidly into the blind spots of queuing vehicles to squeeze into any remaining gap across lane lines

Answer

Hold back behind the give way line until there is enough space on the roundabout to enter without blocking junctions or other road users.
According to the Highway Code, you must not enter a roundabout if your route or the area ahead is blocked by queuing traffic. Holding back behind the give way line keeps the circulatory carriageway open for other vehicles that may be able to exit or pass freely, preventing total junction gridlock.

Step-by-Step Solution

1
Scan the circulatory carriageway and exit roads ahead before committing to cross the give way line.
Identify that slow-moving traffic or a queue is blocking the space immediately past the give way markings.
Observing traffic flow prevents entering a junction that cannot be cleared.
2
Assess whether entering the roundabout will obstruct circulating vehicles or adjacent entry/exit arms.
Recognize that moving forward now would block traffic arriving from or exiting to other directions.
Highway Code Rule 185 states you must not enter a roundabout if your exit is blocked by queuing traffic.
3
Stop and hold your position behind the solid/broken give way line until a clear gap opens ahead.
The entrance remains unobstructed, allowing other traffic to circulate freely.
Maintaining junction clearance prevents gridlock and promotes safe traffic flow.
