Ontario Bus Driver Knowledge Practice Test

After driving through water, it is recommended to test your brakes when safe to do so. Testing your brakes helps to identify any possible damage or malfunction caused by the water. Stopping quickly and firmly from 50 km/h allows for a thorough test of your brakes, as the speed is not too fast or too slow. Testing your brakes at a slower speed, such as 30 km/h, may not provide accurate results and could lead to a false sense of security. Similarly, testing at a higher speed, such as 60 km/h, may be dangerous and could potentially cause further damage. Therefore, it is best to test your brakes at a moderate speed of 50 km/h after driving through water.
