There are several common causes for head-on collisions. These accidents are most likely to occur when one driver due to inattention or, possibly, drunk driving drifts into the oncoming lane and causes a head on collision. It can also occur due to inclement weather (ice or snow) and it can occur when one driver attempts to make a left hand turn across traffic without regard for the oncoming vehicle.
Head-on auto accidents account for a large number of fatalities on the road. According to one recent report, head-on auto accidents accounted for 10% of all auto accident deaths in America even though head-on collisions only account for 2% of all accidents. Other serious injuries that may occur include: broken bones, head injuries, scarring, burns, etc. Common fractures in head-on collisions include ankle and foot fractures, leg fractures, and pelvic fractures. Wrist and elbow injury can also occur depending on the position of your arms on the steering wheel.
Unlike a rear-end accident where the backseat and headrest prevents the passenger from too serious an accident, in a head on collision, the passenger is thrown forward into the airbag, seatbelt, and if unbelted, the windshield. Airbags will almost certainly deploy in these types of car crashes which can result in additional injuries such as injuries to the eyes and ears. Finally, seat belts restrict with tremendous force and can cause damage, in the form of bruises, fractures, punctured lungs and hematomas.
