Speed limits

Speed limits on provincial roadways are established by the Department of Transportation and Infrastructure based on the roadway's design and the environment where it is located.  

Municipalities have the authority to decide appropriate speed limits on municipal roads within their boundaries. 

A posted speed limit is the maximum legal speed limit for that section of roadway based on ideal driving conditions. As good drivers know, driving speed needs to be adjusted for driving conditions. For example, when visibility is reduced due to snow, fog or darkness, drivers should reduce their speed and pay close attention to the roadway. 

Factors taken into consideration when setting the speed limit for a section of roadway include: 

• number and width of driving lanes 
• shoulder width 
• horizontal and vertical alignment (curves and hills) 
• amount of residential and commercial roadside development 
• number of intersections 
• traffic volume (the amount of traffic using the roadway) 
• type and width of sidewalks (or lack thereof) 
• current operating speeds 

Reducing a speed limit does not necessarily discourage speeding. Research has shown that the majority of drivers will drive at a speed that feels comfortable for them. Lowering a speed limit at random increases the difference in speed between the drivers who follow the posted speed and those who drive what feels comfortable, which has been proven to reduce overall safety. This is why speed limits are set based on technical evaluations.  

If you have concerns about drivers going above the legal speed limit or driving without proper care and attention, you should notify your local enforcement agency. Keeping our roadways safe is everyone’s responsibility. 

If you feel the speed limit in an area should be reviewed, please send your request detailing the specific area and concern to [email protected].
