The Texas Department of Transportation (TxDOT) has two types of plates available specifically for older vehicles.
Antique plates are for vehicles at least 25 years old that are used strictly for antique exhibitions, parades, and related activities. (Occasional trips to the repair shop are permitted.)
Only one antique plate per vehicle is issued. To apply for the plate, complete the antique application form and bring it or mail it to your local county tax office. The plate cannot be personalized.
The plate is valid in five-year increments. For vehicles built before 1921, the yearly fee is $8, while it's $10 per year for vehicles manufactured after that. Local additional fees may apply. Find full information here.
Classic plates are also for vehicles that are at least 25 years old. However, vehicles with these plates may be used for routine transportation.
Complete the classic plate form to apply for the plates, and bring it or mail it to your local county tax office.
The plates carry an annual fee of $15, and may be personalized for an extra $40. However, local additional fees may apply.
