The answer options
- When using a roundabout
- When you are in a left-turning queue
- When you are in a queue going straight ahead
- When traffic prevents you from turning rightCorrect
Why that is the answer
Box junctions keep intersections clear so traffic flows smoothly. According to the Highway Code, you must not enter a yellow box unless your exit is clear. The only exception is when turning right; you may enter the box and wait if oncoming traffic or other right-turning vehicles prevent you from turning, provided your exit road is clear. If you are going straight or turning left, you must wait outside the box.
How this comes up in the real test
Questions from rules of the road appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
