What is one action to take if you find yourself driving too closely to another vehicle?

Increasing your following distance is the most effective action to take if you find yourself driving too closely to another vehicle. By creating more space between your vehicle and the one in front of you, you enhance safety and allow for better reaction time in case the vehicle ahead suddenly slows down or stops. This practice is crucial for preventing rear-end collisions, which can occur when drivers are too close behind another vehicle. A greater following distance not only gives you more time to react but also helps you maintain a clearer view of the road and any potential hazards.

The other options, such as accelerating, honking your horn, or changing lanes frequently, are not advisable in this situation. Accelerating could lead to a more dangerous situation if you are too close; honking may not effectively communicate a need for distance; and changing lanes frequently can increase the risk of accidents by contributing to erratic driving behavior. Maintaining a safe following distance is the most responsible and safest strategy when driving.
