Explanation
The speed at which you drive significantly affects your ability to react to hazards and stop safely. At higher speeds, you have less time to perceive and respond to changes in traffic conditions. Maintaining a safe following distance from the vehicle in front of you is important for ensuring you have enough time to react and stop if necessary. For speeds greater than 30 mph, a safe following distance should be 4 seconds or more, allowing you adequate time to assess the situation and take appropriate action to avoid collisions.
