Speed Limit Pilot Project in Alliston

We are excited to announce that the 40km/h area speed limit pilot project is now live in Alliston neighbourhoods. This initiative aims to evaluate the effectiveness of reduced speed limits in improving road safety.

Signs indicating the 40km/h limit have been installed at key neighbourhood boundaries, including:

  • Young Street
  • King Street South
  • Industrial Parkway

As of May 2017, the Highway Traffic Act allows speed limits other than 50 km/h to be established without street-by-street signage in bounded zones.

40 km/h AREA BEGINS signs will be installed at the streets that enter the neighbourhood area and 40 km/h AREA ENDS signs will be installed at the streets that exit the neighbourhood area at the boundary of the designated area.

Aside from the 40 km/h AREA signs at the entrances and exits of the neighbourhood, the 40 km/h speed limit will not be signed along the streets within the neighbourhood area except where existing for school and park zones.

The roads at the boundary of the neighbourhood area including Young Street, King Street South, and Industrial Parkway will remain at their current speed limit.

Please refer to the Council report #ENG-2025-03 below for additional information on the pilot project and a map of the proposed neighbourhood area speed limit signage locations.

Next Steps
During the pilot project, the necessary enforcement measures will be coordinated with the local detachment of the OPP to ensure compliance with the new speed limit.Traffic data will also be collected in collaboration with the OPP and the Town’s contractor to evaluate the effectiveness of the 40 km/h neighbourhood area speed limit. The effectiveness of the pilot project will be reviewed with the Town’s Traffic Advisory Committee to determine the next steps. If this pilot project is successful, neighbourhood area speed limits may be adopted in other individual neighbourhood areas (an expansion of this pilot) or adopted Town-wide in residential areas.
Frequently Asked Questions
Why is a 40 km/h neighbourhood area speed limit pilot project being implemented? 
Reducing speed limits on residential streets and high pedestrian areas makes our streets safer, calmer, and quieter for everyone. Slowing down gives people more time to react to the unexpected, to prevent crashes and reduce the severity of collisions that do happen.

The Dangers of Speeding
Higher speeds can contribute to an increased risk of serious injuries and fatalities:
  1. While speeding, the drivers’ field of vision as well as their situational awareness is drastically reduced. These two important factors are crucial for anticipating and reacting to unexpected events or sudden changes in road conditions.
  2. The faster you are driving, the greater your stopping distance becomes in order to brake, which causes an increased risk of a collision.
  3. Higher speeds cause stronger impacts. If you are in a collision while driving at a higher speed, the blunt force between you and the individual or object you collide with can be much more fatal. This especially applies to those with less protection, such as a cyclist or a pedestrian.
