The answer options
- Maintain your speed
- Increase your speed so they have to join behind you
- Turn on your hazard lights
- Adjust your speed or change lane if safe to do soCorrect
Why that is the answer
When approaching a slip road, watch for traffic joining the motorway. To help them merge safely, you should adjust your speed to create a suitable gap or move into the lane to your right if it is safe to do so. Maintaining your speed or accelerating can force joining vehicles to brake sharply or run out of slip road. Always check your mirrors and signal before changing lanes, as outlined in official guidance.
How this comes up in the real test
Questions from motorway rules 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.
