Headlights
Headlights illuminate the road and make the vehicle visible. Beam discipline (dip for oncoming/leading traffic) is governed by the Vehicle Lights rule. The bright/dim distinction is tested under Rules of the Road, not Section 3, so this control is tagged alleged.
Evidence note: Tested under Rules of the Road, not the official Section 3 controls list.
evidence_strength: alleged.
Purpose
Illuminate the road ahead; bright beam for open road, dipped for meeting/following traffic.
When used
At night and in poor visibility; dip for oncoming traffic and when following closely.
Risks of incorrect use
- Bright beam blinds oncoming drivers
- Driving on parking lights only reduces visibility
Question patterns
- “Which control performs function X?” — component identification.
- Distractor trap: Keeping bright (main) beam on when meeting oncoming traffic.
