Red Seal Transport Trailer Technician Practice Exam

Question: 1 / 400

What must be done to the tires during the pre-trip inspection?

Check for proper tread depth and inflation

During a pre-trip inspection, checking for proper tread depth and inflation is crucial because these two factors significantly affect vehicle safety and performance.

Proper tread depth ensures that the tires have sufficient grip on the road, which is vital for traction, especially in wet or slippery conditions. Tread also helps with heat dissipation and wear, ensuring that the tires can safely support the weight of the vehicle and its cargo.

Inflation is equally important, as properly inflated tires can enhance fuel efficiency, improve handling, and reduce tire wear. Under-inflated tires can lead to blowouts and reduced stability, while over-inflated tires can cause a harsh ride and decreased contact with the road surface.

Thus, checking tread depth and inflation is a key component of ensuring that the vehicle is safe to operate, which is the core purpose of the pre-trip inspection.
