Site traffic and vehicles: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Principal contractor's duties and the traffic plan

  • Traffic of self-propelled vehicles is controlled to protect everyone on the site.
  • The principal contractor plans traffic to limit reversing, installs signs (including speed limits), marks routes and backing areas and has dust controlled.
  • The traffic plan sets out the measures to limit reversing and protect pedestrians, the communication method (two-way radio or hand signals) and a diagram: traffic routes, backing areas, signs, speed limits and signaller positions.
  • The plan is available on site at all times and updated when things change.

Site signaller and reversing

  • The site signaller directs drivers, especially when reversing, and takes training given by an instructor (risks, the plan's rules, equipment, blind spots, communication).
  • They wear fluorescent yellow-green high-visibility clothing, Class 2 or 3, Level 2 (CSA Z96).
  • They stay visible to the driver and out of the vehicle's path.
  • Reversing that could endanger people is done in a backing area closed to pedestrians, or guided all the way by a signaller.
  • The signaller uses a two-way radio; for reversing under 10 m, they may use the hand signals set out in the plan.

Vehicles and equipment

  • A self-propelled vehicle has working brakes and a horn used near pedestrians, doors, corners and dangerous spots.
  • No one but the driver rides on a vehicle without a seat provided for that purpose; no unauthorized person climbs on construction equipment.
  • No worker stays on or in a vehicle if they could be in danger during loading or unloading.
  • To drive a vehicle on site, you need the licence required on public roads or a document proving you can drive it off-road (except a trainee who is accompanied).
  • If the view of a crane, excavator or other equipment operator is blocked (other than when reversing), a worker guides them by hand signals or telecommunication.

Cabs and alarms

  • A cab or protective frame is required if the driver could be hurt by projectiles or falling objects.
  • Every vehicle has a horn within the driver's reach, with a distinct sound loud enough to be heard over site noise.
  • A self-resetting back-up alarm is required on earthmoving machines, trucks rated 2,250 kg or more and vehicles with a blocked rear view.
