Final answer:
The statement that head-on collisions are the most common type of accidents on expressways is false, as they are less frequent compared to rear-end or side-swipe collisions.
Step-by-step explanation:
The statement that head-on collisions are the most common type of accidents found on expressways is false. While head-on collisions can be extremely dangerous and often fatal due to the high speeds and direct impact, the majority of accidents on expressways tend to involve rear-end collisions, side-swipes, or multi-vehicle pile-ups rather than head-on collisions.
Head-on collisions typically occur when one vehicle inadvertently enters oncoming traffic, which is less common on expressways where physical barriers and clear lane markings are designed to prevent such incidents. The severity of head-on collisions can be amplified by the high speeds at which vehicles travel on expressways; however, their overall frequency is less compared to other types of traffic collisions.
