While there is no way of knowing what types of injuries a person will sustain in a car accident, there are many factors that contribute to this. These include but are not limited to:
Minor car accident injuries, such as scrapes and bruises, may heal on their own without medical treatment. On the other hand, there are more serious injuries, such as broken bones and head trauma, which require immediate treatment.
As a motor vehicle passenger, the best thing you can to is protect yourself against a potential accident at all times. This means always wearing a seat belt and obeying the rules of the road.
If you are injured in a car accident, it is best to get checked out by a doctor without delay. Even if you feel okay, there is nothing wrong with being examined just to make sure you remain in good health.
