Explanation
Under ideal conditions (good weather and dry pavement), maintain at least a four-second following distance. Increase this distance in adverse conditions such as heavy traffic, rain, low visibility, or hazardous road surfaces. Failing to maintain adequate spacing significantly increases crash risk. To stay safe, remain alert and always keep a proper following distance from the vehicle ahead.
