Alberta School Bus Rules: When You Must Stop for Flashing Lights

informational·how to guide·Published April 27, 2026

What must you do when a school bus has flashing lights in Alberta?

With flashing red lights, stop before you reach the school bus. Alberta's Driver's Guide says to stop about 20 metres (four to five car lengths) away. On a road with no median, traffic from both directions stops; on a road divided by a median, only traffic behind the bus stops. With flashing amber lights, slow down and be ready to stop. Failing to stop is 6 demerit points.

Where the Alberta school bus rules come from

The law is in the Use of Highway and Rules of the Road Regulation (sections 69 to 73) and the Traffic Safety Act. The Driver's Guide, Spring 2026 explains the rules for drivers. The Demerit Point Program Regulation gives the points. The rules in this post are as of 2026. Confirm the rules with Alberta Transportation and Economic Corridors (alberta.ca) before you drive.

Bus lights	What to do	Who it applies to
Flashing amber	Slow down, so that any pass is made with caution. Be ready to stop: the red lights come next.	Road with no median: traffic from the front and the rear. Road divided by a median: traffic behind the bus.

What do flashing amber lights on a school bus mean?

The bus driver turns on the flashing amber lights when the bus starts to slow down to stop and load or unload students. The amber lights warn you that the red lights will start soon.

The law tells you to slow down so that, if you pass the bus, you pass with caution. The Driver's Guide asks for more: when you meet a bus with amber lights from the front or the rear on a road with no median, be ready to stop. The free practice question on what to do when a school bus turns on amber lights tests this rule.

What do flashing red lights on a school bus mean?

The bus driver turns on the flashing red lights, and the stop arm if the bus has one, when the bus is stopped to load or unload students. The stop arm is a stop sign that swings out from the left side of the bus. The law says you must stop before you reach the bus.

These rules apply whenever and wherever the school bus lights are on. A municipality can also set its own bylaw on when and where school buses use these lights and the stop arm.

Do you stop on a divided highway or a road with a median?

The road has no median, for example a two-lane road or a four-lane undivided highway

Stop for flashing red lights from the front and from the rear. On a two-lane road, both lanes stop. On a four-lane undivided highway, all four lanes stop.

The road has a median (a physical barrier or area that separates the lanes) and you come up behind the bus

Stop for flashing red lights. For amber lights, slow down and be ready to stop, as on a road with no median.

The road has a median and you meet the bus from the front

You do not have to stop. Go with caution and watch for pedestrians. The free question on who must stop on a highway with a median tests this case.

How to stop for a school bus with flashing red lights

1
Slow down at the amber lights
Reduce your speed and be ready to stop. The bus is about to stop, and the red lights come next.
2
Stop about 20 metres back
When the red lights flash, come to a full stop before you reach the bus, about 20 metres (four to five car lengths) away. This gap lets drivers behind you see the lights and the students who cross the road.
3
Stay stopped while the red lights flash
Keep your vehicle stopped while the red lights flash and the stop arm is out. Students can be at risk when they get on or off the bus.
4
Go only when the rules allow it
The law lets you drive past the bus when the bus driver signals that you may go, or when the red lights stop flashing. The Driver's Guide says to stay stopped until the red lights are off and the stop arm is no longer out. Practise this with the free question on a school bus with alternating red lamps.

How many demerit points do you get for a school bus offence?

Failing to stop for a school bus with flashing red lights is 6 demerit points (section 72(1)). Driving past the bus too early, before the signal or before the red lights stop (section 72(2)), is 3 demerit points. The points go on your record when you are convicted.

A fully licensed driver who reaches 15 or more points within 2 years gets a one-month suspension. For learner (Class 7) and probationary (GDL) drivers, the limit is 8 points within 2 years. Read more about demerit points for GDL drivers in Alberta.

Alberta school bus rules: common questions

Do I have to stop for a school bus on the other side of the road in Alberta?

Yes, when the road has no median. On a two-lane road and on a four-lane undivided highway, traffic from both directions stops for flashing red lights. When a median divides the road, only the traffic behind the bus must stop. Oncoming traffic may go with caution and watch for pedestrians.

Can I pass a school bus with flashing amber lights in Alberta?

The law lets you pass only after you slow down, so that you pass with caution. The Driver's Guide says passing is not the safest choice, because the bus may be about to stop for students. Slow down and be ready to stop instead.

Do school bus rules apply on city streets, or only on highways?

They apply on city streets too. The school bus rules use the word "highway", and Alberta's Traffic Safety Act defines a highway as any thoroughfare, street, road, lane or alley that the public may use for vehicles. So the rules cover a residential street as well as a provincial highway.

What counts as a school bus in Alberta?

In Alberta's road rules, a school bus is any vehicle that displays the words "school bus". The rules start when that vehicle flashes its amber or red lights. Only buses that have a stop arm must use one, so treat the flashing red lights alone as the signal to stop.

Will a school bus ticket suspend my learner's or GDL licence?

A conviction for failing to stop adds 6 demerit points. A learner or probationary driver who reaches 8 or more points within 2 years gets a one-month suspension. So 2 more points in that time lead to a suspension. A fully licensed driver's limit is 15 points.
