Texas State Inspection Complete Practice Exam 2026

When a vehicle's muffler is missing, it results in the vehicle failing the inspection. The muffler is a critical component of the exhaust system, designed to reduce noise and control emissions. According to state inspection guidelines, a vehicle must have a properly functioning exhaust system, including the muffler, to minimize noise pollution and ensure compliance with environmental standards.

A missing muffler not only increases the noise level but can also lead to higher emissions, which would be detrimental to air quality. Vehicles that do not meet the specified standards in these areas are deemed ineligible for approval during inspection, leading to an automatic failure. Therefore, it is essential for vehicles to have all necessary components, including the muffler, intact for a successful inspection outcome.
