Difficulty: EasyDriving in Fog and Reduced Visibility

When navigating through thick fog, drivers should decrease their following distance in order to keep the tail lights of the lead vehicle in clear view.

Answer: Answer

Answer

False. Following distance should be increased in fog to allow additional stopping space and reaction time.
The statement is false because safe driving practices require increasing following distance—not decreasing it—when driving in fog, giving drivers adequate space and time to react to hazards.

Step-by-Step Solution

1
Identify the hazard condition presented in the scenario.
Thick fog causing severely reduced forward sight distance.
Reduced visibility hides upcoming obstacles and traffic flow changes.
2
Evaluate the suggested driver action (decreasing following distance).
Decreasing following distance reduces the safety buffer and available braking time.
If the vehicle ahead stops suddenly, a reduced gap greatly increases the likelihood of a rear-end collision.
3
Determine the proper defensive driving rule for reduced visibility.
Increase following distance (e.g., to 4 or more seconds).
Extra space compensates for delayed recognition of hazards ahead.
