When may you enter a yellow box junction?

When there is no traffic
When you are turning left
When your exit is clear
Only in emergencies

The correct answer is: When your exit is clear

Entering a yellow box junction is permitted when your exit is clear. This rule ensures that vehicles do not block the junction, allowing for the smooth flow of traffic and minimizing congestion. When a driver enters a yellow box junction but cannot proceed into the exit lane due to ongoing traffic, they can cause obstruction, which affects all road users. The primary purpose of a yellow box junction is to keep intersections clear, especially during peak traffic times. Therefore, the key condition for entering one is ensuring that the road ahead is unblocked enough for you to exit the junction safely. This understanding contributes to overall road safety and helps maintain an efficient traffic system.
