How can you regulate your speed with the engine of your car?

How can you regulate… — Change to a lower gear

The answer options

Change to a higher gear
Change to neutral
Change to reverse gear
Change to a lower gearCorrect

Why the other options are wrong

“Change to a higher gear” is a distractor. It does not meet the standard the question is testing, which change to a lower gear 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

Changing to a lower gear increases engine braking, which uses the engine's resistance to help control and slow down the vehicle. This is particularly useful when descending steep hills to prevent the footbrake from overheating. Selecting neutral removes engine braking completely, causing the car to coast and reducing your control. A higher gear provides less engine braking, allowing the vehicle to gather speed faster. The Highway Code advises using engine braking to maintain control.

What vehicle handling covers

· Front and rear fog lights and the 100-metre visibility rule
· Descending steep hills in a lower gear and engine braking
· Traffic calming, humps, and driving over tram rails
· Night driving, dipped headlights and dazzle from oncoming traffic

Mistakes learners repeat on this topic

· Leaving rear fog lights on after visibility improves
· Coasting downhill in neutral to save fuel
· Using full beam on a lit motorway or behind another vehicle
· Accelerating between speed humps instead of holding a steady speed

Instructor tip: Any question with fog in it usually turns on the 100-metre rule — check visibility before you check the lights.

How this comes up in the real test

Questions from vehicle handling 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.
