A driver clearly causes an accident; maybe they run a red light or a stop sign. They hit your car. When you get out, though, they're already yelling at you, asking what you think you were doing and blaming you for the crash.
Suddenly, you're concerned. Are they going to fight this? Are they going to report you to the police? Will you have to pay for their mistake?
Fortunately, you have dash camera footage of the crash. You review it and see that it was clearly not your fault. That makes you wonder why they blamed you in the first place. Surely they must have known that the wreck was not your fault?
They may have known that, but people often try to shift blame even when it makes very little sense. One reason is the loss of control that happens in an accident. All of sudden, their day took a massive turn. They worry that they'll have to pay to fix the car, cover your medical bills, and account for many other costs. They feel nervous and unsettled. They may not want to admit their own mistake, so they try to convince everyone else -- and themselves, in many cases -- that it wasn't their fault. It's an instinct as they try to regain control of the situation, even when it's clear to everyone else involved that they really do not have a case.
If you find yourself in this position, you should know what legal options you have to seek financial compensation and to protect yourself from false accusations.
