Make sure that you receive medical care after any car accident – even if you think you were not hurt. Not all injuries have immediate symptoms. Getting treatment later can be used against you, as insurance companies will be quick to say that the failure to get the injury treated immediately is evidence the injury was not serious. One of the most crucial things you can do after an accident caused by a defective highway is to take pictures of the specific hazard involved. Take as many photographs as you can and try to shoot them from different angles and distances. If any people saw your accident, ask them for their names and phone numbers in case they are needed as witnesses. Your last step is to stay quiet about the accident, being especially careful not to post anything about it on social media, which will almost certainly be examined by an insurer. Contact an attorney as soon as you can.
