Why is it necessary to check the vehicle's lights before the TPST?

The necessity of checking the vehicle's lights before the TPST arises from the need to ensure all features are working properly. Properly functioning lights are crucial for both the safety of the driver and others on the road. They play a vital role in visibility during nighttime or in adverse weather conditions, as well as in signaling intentions to other drivers. Completing this check helps to confirm that the vehicle complies with safety regulations and operates effectively, which is a key aspect of the testing process.

While impressive presentation or aesthetic standards may have their place, they do not address the fundamental safety requirements expected during the TPST. Similarly, minimizing maintenance costs is more of a long-term consideration rather than an immediate concern when assessing the suitability of a vehicle for testing. Therefore, confirming that all features, including the lights, are operational is essential for a safe driving experience and necessary for passing the TPST.
