Every question and its answer choices. The correct answers and explanations appear when you take the test above.
What is needed to drive a vehicle on a site, outside of training?
- No document, since the site is not a public road
- The licence required on public roads, or a document proving the ability to drive it off-road
- A verbal OK from the foreman that same morning, before starting the engine
- The 30-hour course card, which allows driving any vehicle on a site
Under the Code, what is a key goal of planning traffic on a site?
- Letting trucks deliver as fast as possible
- Letting each driver choose their own route
- Cutting the number of paid signallers
- Limiting vehicle reversing manoeuvres
Who is responsible for putting up signs, including speed limits, on the site?
- The town where the site is
- Each truck driver
- The principal contractor
- The ready-mix concrete supplier
Where must a site signaller stand while directing a vehicle?
- In the cab, next to the driver, to talk to him
- Out of the driver's view, so as not to distract him
- In the driver's view and out of the vehicle's path
- Right behind the vehicle to see the obstacle
A worker wants to ride on a loader's step to get to the other end of the site. What does the Code say?
- It is allowed if he holds the cab handles tightly
- Only the driver may ride on a vehicle with no seat for a passenger
- It is allowed if he wears his hard hat and safety boots and holds on well
- It is allowed if the loader goes under 10 km/h
How does the signaller communicate with the driver during a 25 m backing manoeuvre?
- By whistle blasts heard across the site
- By hand signals, since it is over 10 m
- By two-way radio communication
- By shouting, while standing behind the truck
When is a cab or protective frame required on a self-propelled vehicle?
- Only when the vehicle travels on a public road, off the site
- When the driver could be hurt by flying or falling objects
- Only when the temperature drops below zero
- Only when the vehicle is more than ten years old
What must a site signaller wear?
- An orange vest of any class, if it is clean, well fitted and easy to see
- A dark rain coat with the company logo
- Fluorescent yellow-green high-visibility clothing, Class 2 or 3, Level 2
- A white long-sleeved shirt with a reflective strip on the back
A truck is being loaded by a crane that swings loads over it. Where should the driver be?
- Standing on the deck to guide the load by hand
- In the cab, engine running, ready to leave if there is a problem
- Out of the vehicle, if they could be in danger during loading
- On the cab roof, to see the crane operator and the load better
What does the Code require for a site signaller's training?
- No training: passing the 30-hour course is enough
- Training by an instructor, covering blind spots and communication among other things
- Training by the vehicle's driver on the same day, before the first backing manoeuvre
- Self-training by reading the traffic plan alone
Which vehicles need a self-resetting back-up alarm?
- Only vehicles that move around the site at night, after dark, without lights
- Only service vans that carry workers
- Only vehicles bought new less than five years ago
- Earthmoving machines, trucks rated 2,250 kg or more and vehicles with a blocked rear view
Which of these must appear on the traffic plan's diagram?
- The names of all subcontractors and their licence numbers
- The rental price of each vehicle used on the site
- The wages of the drivers and signallers
- The location of backing areas and where signallers stand
A truck must back up in an area where people walk. Which options does the Code allow?
- Backing in a no-pedestrian backing area or being guided all the way by a signaller
- Backing with hazard lights on, which replaces the site signaller
- Backing only if a pedestrian agrees to watch the back of the truck for the driver
- Backing slowly while honking, with no other measure, if the driver is very experienced
Site traffic and vehicles: key rules to remember

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.
