Slow-Moving Vehicle Sign

Find out if you need one and how to display it on your vehicle.

Vehicles that need a slow-moving vehicle sign

You need to display a slow-moving vehicle sign if your vehicle is not capable of reaching and sustaining a speed greater than 40 km/hour.

Vehicles that need a slow-moving vehicle sign include:

  • construction equipment
  • farm equipment
  • street sweepers
  • fork lifts
  • low-speed vehicles

If your slow-moving vehicle is towing something, you need to display the sign at the rear of the object being towed.

Vehicles that do not need a slow-moving vehicle sign

You do not need a slow-moving vehicle sign for:

  • bicycles
  • mopeds
  • disabled vehicles being towed
  • vehicles directly crossing a road, as when a farm tractor crosses a road to move from one field to another
  • horse-drawn vehicles driven by people whose religious beliefs do not permit them to use the sign. Instead, the back of the carriage must be outlined with reflective tape visible from at least 150 meters (approximately 500 ft).

Slow-moving vehicle signs are for vehicles only. You can't use them on fixed objects like mailboxes or driveway markers if they can be seen from the road.

Property owners or tenants displaying a slow-moving vehicle sign on fixed objects may be subject to a fine.

Placing a slow-moving vehicle sign

The sign should be placed on the rear of the vehicle between 0.6 meters (2 ft.) and 2 meters (6 ft.) above the roadway. It should be centred from left to right as much as possible.
