Exception details
This memorandum replaces previous policy memo SCB-HDO-2022-02, Design Speed on New Freeways and takes precedence over guidance in the 2023 MTO Design Supplement.
Historically, Ontario applied a Factor of Safety of 20 km/h, unless circumstances warranted a reduction. This policy establishes a consistent approach for application across the provincial freeway network. A Factor of Safety of 10 km/h is established as the baseline on all freeways currently posted at 100 km/h, and all future freeways.
