When can a driver legally exceed the posted speed limit?

A driver is legally permitted to exceed the posted speed limit when overtaking another vehicle. This is because, in certain circumstances, such as when passing a slower-moving vehicle on multi-lane roads or highways, temporarily exceeding the speed limit can be necessary to ensure safety and to complete the maneuver without causing a dangerous situation. However, this should be done with caution, and the driver must always prioritize safety, making sure to return to the posted speed limit as soon as it is safe and practical to do so.

In most other situations, such as in residential areas, on highways, or in school zones, the law requires drivers to adhere to the posted speed limits to ensure the safety of all road users, including pedestrians and cyclists. Exceeding the speed limit in those areas could increase the risk of accidents and lessen the ability to respond to sudden hazards.
