If you've received a ticket as a consequence of a traffic camera, you should contact an attorney right away to obtain a copy of the film. If you need the film to establish your claims, you should also consult a vehicle accident lawyer. This material may be erased or re-recorded in as little as 24 to 72 hours in some places. You won't be able to use this film as proof to claim that you didn't commit the offense after it's gone.
