Why are rear-end collisions common on interstate highways?
Answer: C — Tailgating - driving closely to another driver
Rear-end collisions are common on interstate highways because of tailgating, which means driving too closely to the vehicle in front. When drivers follow too closely, they have less time to react if the car in front suddenly brakes or encounters an obstacle. This can easily result in a rear-end collision. It's essential to maintain a safe following distance to prevent accidents and ensure the safety of everyone on the road.
