Because failing to give the right of way is the most prevalent cause of broadside crashes, T-bone accidents are usually the fault of the vehicle that initially hits another. In T-bone investigations, speeding and running traffic signals are frequently discovered to be the cause of the accident. However, though it's common that the motorist who T-bones another car is often at fault, this isn't always the case. The accident can be caused by either driver. It's also possible that the responsibility will be shared between the two parties.
