Driver conduct and sharing the road: 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 ↗

Driver conduct

When unable to keep up with traffic on a hill, stay right so others can pass; turning on hazard lights is good practice.
Never use your left-turn signal to tell drivers behind that it is safe to pass; it is illegal and confusing.
Avoid pulling out to pass another large vehicle when the speed difference is so small that you block traffic for a long time.
Bluffing (using your size to force through traffic) creates serious hazards.
On a highway at over 60 km/h, a commercial motor vehicle must keep at least 60 m (200 ft) behind other vehicles, except when overtaking.
Speed limiters apply to commercial vehicles built in 1995 or later, with an MGVWR of 11,794 kg (26,000 lb) or more and an electronically controlled engine; they must be set to no more than 105 km/h.
Buses, mobile cranes, motor homes, ambulances and fire apparatus are exempt from the speed-limiter rule.

Precautions

Never let an unauthorized person sit in the driver's seat or operate the truck or its controls.
Back with the utmost care: use all mirrors, look back and, if possible, have someone guide you.

Smaller vehicles

A tractor-trailer needs about twice the stopping distance of an average car and takes much longer to reach normal speed.
When a faster vehicle is passing you, slow enough to let it fit in safely ahead.
Small vehicles often move into a large vehicle's turning space; check that no one has moved into it before you complete the turn.
Motorcycles and mopeds may use the whole lane; their turn signals often do not self-cancel, so make sure they are actually turning.

Cyclists, farm machinery, buses

When passing a cyclist leave at least one metre; change lanes to pass when possible, and do not follow closely (bicycles have no brake lights).
Stop behind a bike box at a red signal, never in it; enter a bike lane to turn right only when it is safe.
Farm tractors and machinery usually travel at 40 km/h or less and show an orange-and-red slow-moving vehicle sign.
You must let a municipal bus re-enter traffic from a bus bay when it signals to leave.

Stopping at railway crossings, school buses and crossings

When a train is coming, stop at least 5 m from the nearest rail or gate; a train can need up to 2 km to stop.
Avoid shifting gears while crossing tracks; if trapped on a crossing, get everyone out and away, then call authorities.
School buses must stop at all railway crossings; buses and public vehicles stop at crossings without gates, lights or a stop sign.
Coming from behind a stopped school bus with upper red lights flashing, stop at least 20 m back; from the front, stop at a safe distance. On a road with a median, only traffic behind the bus stops.
Failing to stop for a school bus: $400 to $2,000 and six demerit points for a first offence; $1,000 to $4,000, six points and possible jail of up to six months for a second within five years.
At a pedestrian crossover, do not pass any vehicle within 30 m of it and wait until pedestrians have fully crossed.
Failing to obey a school crossing guard can bring a fine and three demerit points.

Right-of-way

At an uncontrolled intersection, yield to the vehicle approaching from the right.
At an all-way stop, the first vehicle to stop goes first; if two stop together, the vehicle on the left yields to the one on the right.
Signalling does not give you the right-of-way.

Emergency vehicles

When an emergency vehicle approaches from either direction with lights or siren, slow down, move as far right as possible and stop.
Do not follow within 150 m of a fire vehicle or ambulance responding to a call.
Passing a stopped emergency vehicle or tow truck with lights flashing: slow down and, on a road with two or more lanes, move over one lane if safe.
Failing to slow down and move over: $400 to $2,000 for a first offence, demerit points and a possible suspension of up to two years.
A flashing green light shows a volunteer firefighter or medical responder in a personal vehicle; yield to them.

HOV lanes

Large trucks are not allowed in HOV lanes regardless of how many people are on board.
A commercial vehicle may use an HOV lane only with two or more people and a total length under 6.5 m.
Crossing the striped buffer beside an HOV lane is illegal.

More rules for truck drivers

When several trucks pull onto a highway after a stop, they should leave at intervals that keep enough space between them.
A large vehicle following closely can intimidate drivers of small vehicles and leaves you no room to stop.
Cyclists may use any part of the lane when needed for safety, for example to avoid potholes, debris or sewer grates or to cross tracks at 90 degrees.
When parked at the roadside, check mirrors and blind spots for cyclists before opening a door.
People using motorized wheelchairs or medical scooters are treated as pedestrians; with no sidewalk they travel on the left shoulder facing traffic.
Community Safety Zone signs mark areas with a special risk to pedestrians; traffic fines are increased there.
When entering a road from a driveway or private road, yield to vehicles on the road and to pedestrians on the sidewalk.
At a railway crossing with signals or a gate, wait until the lights stop and the gate rises; never drive around, under or through a gate.
If the driver of a vehicle that passed a stopped school bus is not charged, the registered owner may receive the fine.
Do not drive on or block a freeway shoulder; emergency vehicles use it when all lanes are blocked.
A subsequent move-over offence within five years brings a fine of $1,000 to $4,000.
