Ontario Bus Driver Knowledge Practice Test

When should you always check the condition of your brakes?

1. At high speed

2. At low speed

3. When the vehicle is parked

4. Only during regular maintenance

The correct answer is: At low speed

It is important to check the condition of your brakes while driving at low speeds, in addition to during regular maintenance. Checking at low speeds allows you to better sense and observe any potential issues or malfunctions with the brakes, and take appropriate action before it becomes a safety concern. Checking while the vehicle is parked may not provide an accurate assessment of the brakes' condition, as they are not being actively used. Checking at high speeds is not recommended as it can be dangerous to suddenly brake at high speeds. Regular maintenance should always be done, but it is not the only time to check the condition of your brakes. Maintenance checks may not catch potential issues that may only be apparent while driving. Therefore, it is important to regularly check the condition of your brakes while driving at a low speed.
