Question

Difficulty: MediumDriving in Fog and Reduced Visibility

If dense fog forces a driver to pull off the road and stop on the shoulder, keeping the vehicle's headlights turned on while parked is recommended so approaching vehicles can easily track the car.

Answer: Answer

Answer

False. Drivers who pull completely off the roadway in dense fog should turn off their headlights and foot brake lights to prevent following traffic from tracking their lights off the pavement and crashing into the stopped vehicle.
The statement is false because maintaining active headlights or tail lights on a vehicle parked on the shoulder in severe fog creates a severe rear-end collision hazard. Motorists navigating through low visibility frequently attempt to follow visible vehicle lights ahead, mistaking a parked car for a moving vehicle in the lane. Proper safety protocol requires pulling completely off the paved roadway, turning off headlights and tail lights, taking your foot off the brake pedal, and turning on hazard warning lights.

Step-by-Step Solution

1
Analyze the proposed shoulder-stopping action in dense fog
The scenario describes pulling onto the shoulder during extreme visibility loss while keeping the main headlights continuously illuminated.
To evaluate whether keeping driving headlights on while parked on a shoulder aligns with official DMV traffic safety standards.
2
Evaluate driver optical perception and hazard risks in reduced visibility
In thick fog, drivers instinctively follow red and white light sources ahead. Illuminated lights on a stationary shoulder vehicle deceive trailing drivers into assuming it is active lane traffic.
To identify collision factors caused by light-tracking illusions during adverse weather conditions.
3
Determine correct emergency roadside stopping protocol
Drive completely off the paved surface, turn off driving headlights and tail lights, engage the parking brake, release the foot brake, and turn on emergency hazard flashers.
To state the recognized safety procedure that prevents rear-end collisions in severe fog.
