While tailgating is the most common cause of a rear-end crash, it is not the only one. In some cases, the driver of the car that gets hit in the rear can be the cause of the crash. Examples of the rear driver causing a rear-end collision without tailgating are: driving under the influence (DUI), driving while distracted, or trying to run a red light. Examples of the leading motorist causing a rear-end crash include: deliberately braking suddenly in an act of road rage, driving with taillights or brake lights that do not work, or reversing into the car behind them.
