The answer options
- To allow direct access to overtake
- To allow space to turn around if you are on the wrong road
- To allow you to slot into the traffic flow safelyCorrect
- To continue on the hard shoulder
Why that is the answer
The Highway Code states that when joining a motorway, you should use the slip road to adjust your speed to match the traffic on the main carriageway. Using its full length gives you enough time to find a suitable gap and merge smoothly without forcing other drivers to brake. Turning around on a motorway is illegal and extremely dangerous, and you must never use the entry lane to immediately push out and overtake.
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.
