Question

Difficulty: Very hardDriving in Fog and Reduced Visibility

If dense fog severely reduces forward visibility on a highway, activating your vehicle's emergency hazard flashers while continuing to drive at normal traffic speeds is an authorized practice to alert trailing vehicles of your position.

Answer: Answer

Answer

The statement is false. Emergency hazard flashers should not be activated while moving in active lanes during fog, as they falsely signal a stationary vehicle to trailing traffic and disable directional turn signals. Additionally, maintaining normal speed in severe fog violates the Basic Speed Law.
The correct response recognizes the statement as false because hazard flashers are designated for stopped, stalled, or disabled vehicles. Operating them while driving in motion misleads trailing drivers and overrides standard turn signaling. Furthermore, driving at normal speeds under dense fog conditions violates the Basic Speed Law.

Step-by-Step Solution

1
Analyze the legal and practical purpose of emergency hazard flasher lights.
Hazard flashers warn other road users of a stationary hazard, accident scene, or disabled vehicle.
Activating hazard lights while driving in motion creates hazardous ambiguity, making trailing drivers believe the vehicle is stopped in the roadway.
2
Evaluate vehicle operation speed under restricted visibility.
The Basic Speed Law mandates slowing down below posted limits whenever weather or visibility conditions impair safe driving.
Maintaining normal speed when forward sight distance is severely limited prevents stopping within the clear distance ahead.
