The answer options
- 70mphCorrect
- 60mph
- 50mph
- 40mph
Why that is the answer
The national speed limit for cars and motorcycles on a dual carriageway is 70mph, unless signs indicate a lower limit. A dual carriageway is a road with a central reservation separating opposing traffic flows. Do not confuse this with a single carriageway, where the national speed limit for these vehicles is 60mph. The Highway Code sets these default limits to maintain safe traffic speeds across the UK road network.
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.
