Behaviours – Courtesy and Sharing the Road

Sharing the Road with Heavy Vehicles

Heavy vehicle drivers need room to manoeuvre because their vehicles are longer, wider, taller and heavier. Give them the space they need!

Near heavy vehicles...

Avoid a heavy vehicle’s blind spots, because the driver cannot see you when you are there.

  • Stay either far ahead of or far behind a heavy vehicle.

Keep your distance. If you don’t, you won’t be able to see signs, traffic lights or even unexpected situations in time. It’s like driving with a wall in front of you.

  • If the heavy vehicle driver brakes suddenly, you won’t be able to avoid a collision.
  • Be attentive and careful, anticipate the driver’s moves and stay far behind the heavy vehicle.

Respect stop lines. When you don’t, you take up space heavy vehicle drivers need in order to turn.

  • You must stop behind the stop line painted across the pavement.
  • If there is no stop line, you must stop behind:
    • the pedestrian crosswalk
    • the spot where the sidewalk ends
    • the edge of the roadway

Do not cut off heavy vehicle drivers, as they won’t have enough space to brake safely. As well, they may not even see you.

  • Wait until you can see the entire heavy vehicle in your central rearview mirror before merging back into the lane ahead of it.
  • When you pass a heavy vehicle at 100 km/h, leave approximately six vehicle lengths between you and the heavy vehicle before merging back into the lane.

Right turns: Heavy vehicle drivers need a lot of space to turn. When you place yourself to the right of a heavy vehicle, you are in its blind spot and the driver can no longer see you.

  • Be attentive and careful, anticipate the driver’s moves and stay well behind the heavy vehicle.

Awareness tools

A variety of tools have been developed (in French only) to inform drivers of the safe practices they should adopt when driving near heavy vehicles.
