Final answer:
Rear-end crashes in work zones are caused by following too closely or tailgating.
Step-by-step explanation:
Rear-end crashes in work zones are most commonly caused by following too closely or tailgating. Tailgating occurs when a driver does not maintain a safe distance from the vehicle in front of them. This can lead to rear-end collisions if the vehicle in front slows down or stops suddenly.
For example, if a driver is not paying attention or is distracted, they may not notice when the vehicle in front of them slows down. As a result, they may not have enough time to brake and avoid a collision.
To prevent rear-end crashes in work zones, it is important to maintain a safe following distance, be aware of road signs and signals, and avoid distractions while driving.
