What is the maximum speed limit for buses on highways in Ontario, unless otherwise posted?

Answer: C — 100 km/h

The maximum speed limit for buses on highways in Ontario is 100 km/h unless otherwise posted. This speed limit is established to ensure the safety of both the bus occupants and other road users. Buses are larger vehicles that typically take longer to accelerate and stop compared to smaller vehicles, so the limit is set to balance efficiency with safety. By limiting the speed to 100 km/h, the regulation allows buses to maintain a steady flow of traffic while still providing a level of safety. Drivers must remain vigilant and adhere to this maximum speed, adjusting their speed if conditions such as weather, road work, or traffic require it to be lower. Understanding this speed limit is crucial for bus drivers, as it directly influences their driving behavior and compliance with traffic laws.
