Highway sign
Highway 401 marker
A green crown-shaped shield with a route number marks a King’s Highway, including the 400-series freeways such as the 401 and 400. These controlled-access highways have higher speed limits and rules that exclude some road users.
When you see it
- ◆ G1 drivers may not drive on 400-series highways unless a licensed driving instructor is with them.
- ◆ Pedestrians, cyclists, and slow vehicles are not permitted.
- ◆ Enter from the on-ramp and match the speed of traffic before merging.
The default maximum on most 400-series highways is 100 km/h, with some sections posted at 110 km/h.
