Explanation
Always maintain a safe following distance from the vehicle ahead. At highway speeds under good conditions (clear weather, normal traffic), apply the four-second rule. This provides sufficient reaction time to avoid collisions in emergencies. By keeping at least four seconds of space, you ensure adequate stopping distance if the vehicle ahead brakes suddenly.
