Whatever you do, don’t accept any liability if you think the other driver may have been in the wrong. It may be that both drivers had some fault and this is something that is best dealt with and determined by an engineer. You may still be able to recover part of your claim. Another thing to consider is contributory negligence. This is when you contribute in some way to your own misfortunate and injury. If you suffer injuries in a car accident but you were not wearing a seatbelt you will be found to have contributed/added to your own pain. This means you will be able to recover part of your claim.
What do I do if the accident was 50/50?
