Ontario Bus Driver Knowledge Practice Test

The recommended following distance for buses in ideal road conditions is four seconds. This distance is based on the need for larger vehicles to have ample time to react and stop safely. Buses, due to their size and weight, require a greater distance to come to a complete stop compared to smaller vehicles. By maintaining a four-second gap, bus drivers ensure they have enough time to assess road conditions, respond to the actions of vehicles ahead, and provide for safe braking without risking a collision.

This four-second rule also helps to accommodate for various factors, such as potential sudden stops by the vehicle in front, road conditions, and the bus's braking capabilities. The added time allows for better judgment and enhances overall safety for passengers and other road users.
