Most of Alberta's rules about other road users exist because hitting them isn't survivable the way a fender-bender is. A child stepping out from behind a school bus. A paramedic working on a shoulder. A cyclist in a door zone. A truck that needs eight seconds to stop. Each has its own rule, and every one of those rules is built around the same fact: you can see less than you think you can. Here's what the law requires in each case, including one spot where Alberta is looser than drivers assume.

| School bus, flashing red lights | Stop in both directions unless the road is divided |
|---|---|
| Emergency vehicle approaching, siren on | Pull to the curb, parallel to the road, and stop |
| After it passes | Do not drive within 150 m of it while lights or siren are on |
| Stopped roadside vehicle, lights flashing | Move to the far lane, or slow to at least 60 km/h or the posted limit, whichever is lower |
| That penalty | $243 fine and 3 demerits, plus a speed fine; speed fines are doubled |
| Passing a cyclist | Alberta sets no fixed minimum distance — leave a safe distance and pass at a moderate speed |
School buses: the red lights aren't advisory
When a school bus shows flashing red lights, traffic stops. Vehicles from both directions, behind the bus and coming toward it, and you stay stopped until the lights stop flashing.
The exception is a divided highway. If you're going the other way on a road physically split by a median or barrier, you don't have to stop, because the children won't be crossing your side. A painted centre line doesn't make a road divided. You stop.
Alberta also uses amber flashing lights to warn that the bus is about to stop and the reds are coming. Amber means slow down and get ready to stop. It doesn't mean floor it and get past.
Why the rule is written like this. A stopped bus is a big wall you can't see through, and children are short. The one thing a driver coming up on a stopped bus cannot do is see a child in front of it. Passing the bus is exactly the move the law targets because it puts your car where a crossing child would be, at the moment you can least see them.
Emergency vehicles: pull right, stop, then stay well back
Siren behind you. Alberta's instruction: pull over immediately, as close to the curb as you can, staying parallel to the road, normally to the right. Stop and stay stopped until it's passed and it's clear no more are coming. Signal before you rejoin traffic.
The variants matter:
- At an intersection, generally get through it and then pull to the right curb. If you can't clear it safely, get as far from the centre as you can and leave the biggest path possible.
- On a divided highway with two or more lanes, or a one-way, pull parallel to the nearest available curb.
- From a centre lane on a multi-lane highway, move toward the right.
The rule drivers break most often is the one that applies after the vehicle goes by: you must not drive within 150 metres of an emergency vehicle with its siren or flashing lights on. Roughly a football field and a half. Tucking in behind an ambulance to use the gap it opens is an offence.
Slow down and move over
A separate, newer duty covers stopped roadside vehicles with flashing lights: police, ambulances, fire trucks, tow trucks, maintenance vehicles. In the lane nearest them you must move over to the far lane, or if you can't do that safely, slow to at least 60 km/h, or the posted speed limit, whichever is lower.
Non-compliance is a $243 fine and 3 demerit points, plus a speed fine. On top of that, speed fines are doubled when construction workers or any stopped roadside vehicle with flashing lights are present; the doubled bands top out at $1,200 in the published table.
For a GDL driver the 3 demerits are the expensive bit. With an 8-point ceiling, one lapse on a highway shoulder eats more than a third of the allowance.
Cyclists: what Alberta actually requires
A widely repeated claim needs correcting here. Alberta doesn't have a one-metre passing law for cyclists. Several provinces do. Alberta's requirement, in the province's own cycling guidance, is to leave a safe distance between the vehicle and the bicycle and pass at a moderate speed.
"Safe distance" is a judgement, not a measurement. On an urban street it means changing lanes to pass, the same as you would for a slow car. A cyclist needs room to swerve round a drain grate, a pothole or an opening car door, and you can't see any of those from behind them.
Two related points from Alberta's cycling material:
- The door zone, roughly a one-metre band beside parked cars where an opening door can hit a cyclist, is why cyclists ride further out from parked cars than drivers expect. They aren't blocking you. They're staying out of a hazard.
- Cyclists have the same right to the road as drivers, and the same obligations at signs and signals.
So: pass with a full lane change where you can, wait where you can't, and check the mirror and blind spot for cyclists before you turn right or open a door.
Pedestrians
You yield to pedestrians at crosswalks, marked and unmarked. The rule that prevents the worst outcomes is the ban on passing a vehicle stopped at a crosswalk. The stopped car is both a warning and a wall.
In school and playground zones, passing another vehicle going the same way is prohibited while the zone is in effect. The hours are very different between the two zone types; our speed limits and zones guide lays them out.
Large trucks: three things they can't do
Sharing a highway with heavy trucks is mostly about physics, not a specific rule:
- They can't see you where you probably are. A loaded tractor-trailer has big blind spots down both sides (worst on the right) and straight behind. If you can't see the driver's mirrors, the driver can't see you.
- They can't stop like you. A loaded truck at highway speed needs far more room than a car. Cutting in front of one and then braking takes away the space it needs.
- They can't turn tightly. A truck turning right often swings left first and borrows part of the next lane. Fill that gap and you're where the trailer is about to be.
Add spray. Passing a truck in heavy rain or slush means seconds of near-zero visibility. Commit to the pass or stay back. Hesitating alongside is the worst of the three.
Snowplows and maintenance equipment
Don't pass a working snowplow. The road ahead of the plow is, by definition, the bit that hasn't been cleared, and plows throw snow and de-icing material in a wide arc that blinds you right as you come alongside. They also run well under the posted limit and sometimes work in echelon across several lanes. There's no gap to take.
Same logic for graders, sweepers and mowers: slow, stay back, pass only when you can see clearly past the machine and there's room to do it.
Animals and rural roads
On rural Alberta highways, deer at dawn and dusk and livestock near open-range signs are real hazards. The standard advice holds: brake, don't swerve. A controlled collision with an animal is more survivable than losing the car into oncoming traffic or a ditch. See one animal, expect more behind it.

About This Guide
Written and edited by Mark Goh, editor of Alberta Class 7 Practice Test. It includes one correction on purpose: Alberta does not have a one-metre cyclist passing law, despite a claim that circulates widely in driving-test material.
Fact-checked against the Government of Alberta pages listed below. Fines, demerit values and fees change. Some amounts (registry service charges, for one) aren't set by the province at all; each registry agent sets its own within a published cap. Where that's the case, the text says so instead of quoting one number as if it applied everywhere.

Frequently Asked Questions
When do I have to stop for a school bus in Alberta?
When a school bus shows flashing red lights, from both directions, unless you are on a divided highway travelling the opposite way to the bus. Wait until the lights stop flashing before you move.
Does Alberta have a one-metre passing law for cyclists?
No. Alberta sets no fixed minimum passing distance for cyclists. The rule is to leave a safe distance between your vehicle and the bicycle and pass at a moderate speed, which on most streets means a full lane change where one is available.
What is the penalty for not slowing down and moving over in Alberta?
A $243 fine and 3 demerit points, plus a speed fine. Speed fines are doubled when construction workers or any stopped roadside vehicle with flashing lights are present.
