Frequently Asked Questions
What injuries are most common in car accidents?
Car accidents usually cause whiplash, head and neck injuries, broken bones, and cuts or bruises from broken glass or sudden impact. Severity depends on speed, the angle of the collision, and whether seat belts were used.
What are the most common causes of car accidents?
Distracted driving, speeding, following too closely, and impaired driving are frequent causes. On ramps and merge areas, misjudged gaps and sudden braking are also common factors.

Higher speeds give drivers less time to react and increase the force of impact, which raises the likelihood of serious injury even in a short-distance collision like a ramp merge.
