The answer options
- Leave your parking lights onCorrect
- Leave your dipped headlights on
- Leave your main-beam headlights on
- Leave your dipped headlights and fog lights on
Why the other options are wrong
- “Leave your dipped headlights on” is a distractor. It does not meet the standard the question is testing, which leave your parking lights on 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
When parking on a road in fog, you must leave your parking lights on so other road users can clearly see your stationary vehicle. The Highway Code requires this to prevent collisions in reduced visibility. You should not leave dipped headlights or fog lights on when parked, as these will quickly drain your vehicle battery and cause unnecessary glare for approaching drivers.
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.
