37. 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.

What does a mandatory-direction sign mean?
It requires drivers to follow the direction or one of the directions shown by the arrow or arrows.
Does the sign impose a speed limit?
No. Drivers must follow the applicable general, zonal or posted speed limit and reduce speed when necessary to complete the required movement safely.
Does the sign give you priority?
No. You must still obey traffic lights, priority signs and the ordinary rules concerning oncoming traffic, pedestrians, cyclists and other road users.
Can a mandatory-direction sign apply to only one lane?
Yes. When it is positioned above a particular lane or clearly associated with that lane, it normally applies only to traffic using that lane.
Must you use an indicator?
Yes, when the required movement involves turning or changing position and local law requires signalling. The sign does not replace the obligation to indicate.
