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 the other options are wrong
- “To allow direct access to overtake” is a distractor. It does not meet the standard the question is testing, which to allow you to slot into the traffic flow safely does. Picking it in the real test costs a mark you cannot get back, and with a pass mark of 43 out of 50 you only have seven to spare.

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.
What motorway rules covers
- · Joining and leaving via slip roads and matching traffic speed
- · Lane discipline and who may not use the right-hand lane
- · Red X signals, variable limits and emergency refuge areas
- · Breakdowns, hard shoulder use and where to wait
Mistakes learners repeat on this topic
- · Treating the right-hand lane as a permanent fast lane rather than for overtaking
- · Stopping on the hard shoulder for a phone call or a rest
- · Driving in a lane marked with a red X because it looks clear
- · Reversing back along a slip road after missing an exit
Instructor tip: Every breakdown answer follows the same order: get left, get out on the nearside, get behind the barrier, then call.
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.
