Question

Difficulty: MediumDriving in Fog and Reduced Visibility

When forced to pull completely off the roadway and stop due to dense fog, you should keep your foot pressed on the brake pedal so that approaching drivers can see your brake lights.

Answer: Answer

Answer

False. When pulling off the road in severe fog, drivers should turn off all main exterior lights and remove their foot from the brake pedal once safely stopped so following traffic does not mistake the vehicle for moving traffic and steer off the roadway.
The statement is false because keeping your foot on the brake pedal illuminates the brake lights, which can trick drivers approaching from behind into believing your vehicle is still driving in a travel lane, causing them to steer off the road and collide with your stopped car.

Step-by-Step Solution

1
Evaluate the psychological effect of brake lights on other drivers in dense fog conditions.
Determined that motorists driving through reduced visibility frequently track and follow the lights of vehicles ahead to stay on course.
Visual references are severely limited, making active light sources the primary cue drivers use for spatial orientation.
2
Identify proper parking protocols when stopping off the pavement during severe low-visibility hazards.
Recognized that holding the brake pedal keeps brake lights illuminated, creating a dangerous trap where trailing cars follow the lights off the road.
Vehicles stopped off the roadway must eliminate active travel lights (like brake lights) and set emergency brakes to prevent rear-end collisions.
