What is the statute of limitations for traffic tickets in the state of Texas?
It sounds like you may have received one of those “old” tickets that have been coming out of Texas lately, some even back to the Eighties. If it is from a “law office” be very skeptical. Send in a demand for verification and a request for the court record. Usually they can’t produce anything and will have to drop it. Do not ignore the letter since it is possible they could suspend your license.
