Vehicles that require the sign
You must display a slow-moving vehicle (SMV) sign as a warning to other drivers if your vehicle is not capable of reaching and sustaining a speed greater than 40 km/h.
Vehicles that need a slow-moving vehicle sign include:
- construction equipment
- farm equipment
- street sweepers
- fork lifts
- low-speed vehicles
You do not need a slow-moving vehicle sign for:
- disabled vehicles being towed
- vehicles directly crossing a road, for example, 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
Horse-drawn vehicles driven by people whose religious beliefs do not permit them to use the sign must have the back of the carriage outlined with reflective tape that is visible from at least 150 metres (approximately 500 feet).
Get a sign
You can buy a slow-moving vehicle sign from local hardware or other retail stores.
Where to place
The sign should be:
- placed on the rear of the vehicle between 0.6 metres (2 feet) and 2 metres (6 feet) above the roadway
- centred from left to right as much as possible
If your slow-moving vehicle is towing something, you need to display the sign at the rear of the object being towed.
Slow-moving vehicle signs should not be used on fixed objects such as mailboxes or driveway markers. You can be fined if you display a sign on a fixed object and the sign is visible from the road.
