The sooner the better. Some people don’t want to be seen as running to a lawyer the minute that tragedy strikes, but there is nothing more important than getting to the lawyer as soon as possible. Skid marks wash away, witnesses disappear, videos are over over-written and that’s just 3 of a thousand things that can and will change over time. The lawyer is in the best position to help you when he or she is given early access to information, evidence, and witnesses.
