The answer options
- One-way streets
- 30mph roads
- After a bend
- Before a dip in the roadCorrect
Why that is the answer
You must avoid overtaking before a dip in the road because oncoming vehicles can easily be hidden from view. The Highway Code stresses that you should only overtake when you have a clear, unobstructed view of the road ahead. You can overtake on one-way streets or 30mph roads if safe. After a bend, your vision improves, but overtaking before a dip restricts your line of sight, making it extremely dangerous.
How this comes up in the real test
Questions from alertness 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.
