EMISSIONS TEST FAILURESIf your vehicle fails the emissions test, you must have the vehicle repaired, after which it must pass the after repairs emissions test. The vehicle can be repaired at any of the recognized emissions repair facilities or any other repair shop of your choice. The advantage of using a recognized emissions repair facility is that all costs of labor and parts count towards the total that you are required to spend in case you have to go for an emissions test waiver. If your vehicle is unable to meet the emissions standard following the necessary repair work, you may be able to obtain a waiver issued by the Texas Department of Public Safety. A waiver can be issued if you can prove that your vehicular usage is minimal, or if your vehicle emission levels are low, or if the cost of meeting the emission standards are too high. You can even request more time to carry out the necessary repairs. Cars older than 24 years are considered antiques and are exempt from the emissions test.
