The answer options
- To allow pedestrians to cross
- To separate traffic lanes
- To increase traffic speed
- To decrease traffic speedCorrect
Why that is the answer
Road humps, chicanes and road narrowings are traffic calming features designed to decrease traffic speed, particularly in residential areas and near schools. Physically altering the road forces drivers to slow down, reducing the likelihood and severity of collisions. While lower speeds make roads safer, these measures are not designated pedestrian crossings, nor are they meant to separate traffic lanes. Always negotiate them at a safe, steady speed.
How this comes up in the real test
Questions from safety and your vehicle 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.
