What is recommended if the driver is not fully alert regarding following distances?

When a driver is not fully alert, it is crucial to increase following distances significantly to ensure safety. By doubling the recommended following distance, the driver allows more time to react to any emergencies or unexpected changes in traffic conditions. This additional space accommodates for slower reaction times that often accompany diminished alertness, providing ample time to stop safely or maneuver around obstacles.

Maintaining the same following distance or reducing it could lead to dangerous situations, especially if the driver’s reflexes are slower. Enhanced following distances serve as a precautionary measure, prioritizing safety for both the driver and other road users. Therefore, the correct approach is to increase by two times the normal following distance to mitigate risks effectively.
