What is inspected inside the vehicle during the Texas Vehicle Safety Inspection?

During the Texas Vehicle Safety Inspection, the inspection of the windshield wiper controls and turn signals is crucial for ensuring that the vehicle is safe for operation on the road. These components are vital for the driver's visibility and communication with other road users. Properly functioning windshield wipers are essential for maintaining clear visibility in adverse weather conditions, while working turn signals are necessary for indicating turns and lane changes to other drivers, which enhances overall safety.

Other components, such as the spare tire condition, engine noise, and temperature, might be relevant in certain contexts, but they do not fall under the internal inspection criteria for this certification. Similarly, the functionality of the radio does not impact the safety of the vehicle and is therefore not part of the inspection process. Focusing on components that directly affect the vehicle's operational safety is what the Texas Vehicle Safety Inspection is fundamentally about.
