Night DrivingStandalone practice
When following another vehicle at night, when must high beams be dimmed?
At night, blue car A follows silver car B on a straight road. The card says the illustration is not to scale.
Correct answer: Within 150 metres
Why
At night, dim high beams when following or approaching the rear of another vehicle within 150 metres. Low beams reduce glare in the other driver’s mirrors. This is a dimming threshold, not a safe following-distance rule.
