Mandatory directionCanada
20. Mandatory direction
A mandatory-direction sign requires drivers to travel only in the direction or one of the directions indicated by its arrow or arrows. It may require traffic to continue straight ahead, turn, or pass an obstacle on a specified side.
The sign does not itself determine priority or speed. Drivers must still use the appropriate lane, signal when required and give way according to local traffic signs and regulations.

How can a mandatory turn be indicated in Canada?
Mandatory movements in Canada may be shown by regulatory signs, lane-direction arrows or turn-only indications. Do not expect the sign shape to be identical to the European blue circular sign system.
Can I choose another turn if the mandatory-direction arrow is inconvenient in Canada?
No, unless another applicable sign, lane instruction or authorised traffic direction lawfully permits it. Plan a permitted alternative route; do not make an abrupt or prohibited turn to reach your destination.
Does a mandatory-direction sign give me priority over pedestrians in Canada?
No. It tells you which way to move, not who goes first. Check traffic lights, other priority signs, pedestrians and cyclists, and give way when required before completing the manoeuvre.
