DVSA-style practice question · Rules of the Road ## The answer options - 70mph**Correct** - 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.

[Book my theory test](/theory/signup) ## Passed your theory? Get the practical booked Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
