When left hook bicycle accidents occur, it is important to determine whether drivers or cyclists are at fault. According to the Centers for Disease Control and Prevention, the risk of involvement in a crash resulting in injury or death is significantly greater for cyclists than it is for motor vehicle drivers or passengers, despite bicycles only accounting for 1% of U.S. travel. Drivers often do not see or claim to have not seen bicyclists, which can result in them failing to take appropriate action to avoid potentially serious collisions.
