Speed Management
Learn about speed display boards and how they are used to slow traffic.
To manage speeding on our streets, The City of Markham uses speed display boards to improve driver behaviour.
You’ll see speed display boards all over Markham. These devices use radar technology to detect vehicle speeds and display it back to the driver. They let drivers know if they are driving too quickly and need to slow down. Studies show that vehicle speeds are reduced by up to 20 percent when these signs are placed.
- Speed Display Board Locations
The City has twenty four speed display boards. We put them on streets for a three month period. To consider locations for the devices, our staff review traffic conditions on the street. If staff can confirm there is a speeding problem and existing traffic signs and other measures are not working, a speed display board may be used.
If you would like your street to be evaluated, please contact the Contact Centre.

- Enforcement
York Regional Police enforce the speed limit across the City. They also look for people who break other traffic rules. If you think that a street needs more police enforcement, please contact York Regional Police. We also encourage you to use York Region’s Road Watch Program. There, you can report aggressive drivers to police.
