Texas has a 2 year statute of limitations for all injuries. This means that if you have not filed a lawsuit within that time period, you lose the right to pursue the person who caused you injuries. Contacting a lawyer soon after the collision is the best choice to allow for an investigation, getting witnesses, assisting with medical claims, and handling the insurance carrier. Do not try to resolve your claim with the other driver’s insurance company yourself. They do not owe you any legal duty to fairly and reasonable resolve your injury claim.
