What is the maximum speed limit on most Ontario highways?

The maximum speed limit on most Ontario highways is set at 100 km/h (62 mph). This limit is established to balance safety with the efficient flow of traffic. It is designed to accommodate standard vehicles and allows for safe travel while considering the road conditions and the types of vehicles that commonly utilize these highways.

Exceeding this limit can increase the risk of accidents, as higher speeds reduce the driver's ability to react quickly to sudden changes in road conditions or other vehicles. Additionally, speed limits are enforced not just for safety but also to minimize noise and environmental impacts in surrounding areas. While certain highways may have different speed limits, 100 km/h is the typical standard for major routes in Ontario.
