Limit your speed

Speeding is the primary cause of 25% of fatal collisions in Calgary. Remember to slow down and drive the posted speed limit.

Limit Your Speed campaign

Please note that Limit your Speed signs are only installed at specific locations where The City’s speed studies have indicated a need. They are not installed on a request basis.  Communities wishing to request speed signs should apply through the SLOWS program.

Signs in the community

Thirteen Interactive Speed Limit Observation and Warning System (ISLOWS) solar powered signs have been installed in various communities throughout Calgary to alert motorists if they are driving faster than the posted speed limit. These devices are useful reminders to motorists to slow down. The signs are installed at specific locations where our speed studies have shown issues. Locations identified for this year are shown on the ISLOWS location map and are listed below:

Slow down when passing emergency vehicles

The City is also reminding motorists that they must slow to 60 km/h, or less if the posted speed is lower, when passing emergency vehicles or tow trucks stopped with their lights flashing. Fines for speeding in these areas are double the regular amount.

Limit your risk of being in a fatal crash

Driving above the posted speed limit reduces your ability to steer safely around curves or objects on the road; reduces the effectiveness of roadside hardware such as barriers, crash cushions and bridge rails; and decreases your field of vision and your peripheral vision. Limit your speed…It's worth it!
