A solid amber traffic signal means stop if you can do so safely. Flashing or rotating amber warning lights on a vehicle are a different matter: provinces allow them only for specified vehicle classes or under a permit. Transport Canada sets manufacturing standards, while provinces control where and when you may use a device.
TL;DR:
- SAE certification describes a light’s performance, but provincial rules determine whether your vehicle may use it, and a permit may impose operating conditions.
- British Columbia permits may require highway parking when no alternative is workable and may set mounting, stationary use, indicator, or device count conditions.
- Nova Scotia sets a 60 km/h limit or the lower posted speed near stopped vehicles with flashing lights; Ontario penalties include fines and demerit points.
- Before buying, match the vehicle’s primary use and device type to provincial rules, then collect manufacturer visibility specifications and keep them with permit records.
What does a solid amber traffic signal mean for drivers?
A solid amber signal tells you red is about to appear. Ontario’s Driver’s Handbook says to stop if you can do so safely, and to continue only when you are too close to stop. Never speed up to beat the light.
This is a right-of-way signal at an intersection. A flashing amber light on a tow truck, plow or work vehicle is a separate warning device that marks a hazard or work activity. The two are governed by different rules and should not be confused.
A few quick examples show the difference:
- You are approaching, travelling at a normal speed, and the light turns amber: stop smoothly.
- You are already in the intersection or too close to stop without hard braking: continue through.
- You see amber and accelerate to get through before red: that is unsafe and not what the rule intends.
Who may use flashing or rotating amber lights in each province?
Provinces and territories decide which vehicle classes may carry amber warning lights and what permits apply. Transport Canada’s role stops at manufacturing standards. In practice, if your vehicle’s primary duty matches an authorised class, amber is commonly permitted; otherwise you need to look at permit routes.
- Ontario: Tow trucks, snow plows and certain commercial vehicles commonly use amber warning lights. We cover the details in our Ontario guide to amber warning lights.
- British Columbia: The Amber Flashing Lamp Reference Guide separates 360-degree warning devices from directional flashing optical devices such as arrow boards.
- Alberta and Saskatchewan: Alberta ran a tow truck blue light pilot that allowed blue lights only alongside amber, used while stationary. Saskatchewan amended its law for roadside assistance vehicles. Our Alberta and Saskatchewan tow truck guide goes deeper.
- Québec: The SAAQ explains which vehicles are automatically authorised and where a permit is required.
- New Brunswick and Nova Scotia: Both focus on how drivers must respond to flashing lights, covered in the move-over section below.
For a consolidated overview, see our warning light regulations page and our broader piece on amber light legality in Canada.
Which permit conditions and device definitions should you watch for?
British Columbia’s guide defines a 360-degree warning device as one meant to be seen from all sides, and a directional flashing optical warning device as one aimed in a set direction, such as an arrow board. The device class shapes where it may be mounted and how it may be used. BC’s permit pre-screening adds that permits are for vehicles that must park on a highway with no workable off-highway option.
Conditions you may encounter include stationary-only activation, roof mounting, an in-cab on/off indicator, a cap on the number of devices, and visibility distance requirements. SAE certification describes performance. It does not grant operational permission on its own.
- Check your provincial permit guide.
- Confirm how your device is classified.
- Gather the SKU specifications for the application.
Pro Tip: Keep the manufacturer’s specification sheet with the permit file, since reviewers often ask for it.
What are your move-over and slow-down duties?
Most provinces require you to slow down and, where safe, move over for stopped vehicles with flashing lights. A flashing amber on a stopped vehicle is your cue to follow these rules.
- Ontario: Drivers can be charged for failing to slow down or move over for stopped emergency vehicles or tow trucks, with fines, demerit points and possible licence suspension.
- Nova Scotia: The slow down, move over guidance sets a reduced speed of 60 km/h or the posted limit if lower, with fines for violations.
- New Brunswick: Drivers are told to slow down and move over, with fines and demerit points.
- British Columbia: The Motor Vehicle Act Regulations set separate speed and lane-change rules, including for divided roadways.
These rules protect roadside workers and responders, and they apply whenever the lights are flashing.
What must fleet buyers check before fitting amber warning lights?
Work through this list before you buy:
- Confirm the vehicle’s class and primary use.
- Verify the device type, whether 360-degree or directional.
- Collect the manufacturer’s visibility specifications.
- Check for stationary-only activation and roof-mounting clauses.
- Confirm any in-cab indicator or maximum device count.
- Keep documentation with each vehicle and call the provincial permitting office on unclear cases.
SAE compliance helps, but as Transport Canada notes, provinces decide operational use, so a light legal in one province may not be in another. Operators are also responsible for matching their lighting to provincial regulations. For Ontario specifics, our Book 7 guide is a useful companion.
Pro Tip: Ask us for SKU-level product guidance before purchase, and review the product page for each item.

FAQ
Are amber lights legal in Canada?
Yes, but only for authorised vehicle classes or under a provincial permit. Transport Canada sets manufacturing standards, while each province controls operational use.
What does a solid amber traffic light mean?
It means red is about to appear. You should stop if you can do so safely, as Ontario’s Driver’s Handbook explains. Continue only if stopping would be unsafe.
Does SAE certification make an amber light legal everywhere?
No. SAE ratings describe performance, not permission. Legality depends on provincial rules and any permit conditions that apply to your vehicle.
Why do drivers have to move over for flashing amber lights?
Flashing lights mark a stationary hazard or worker. Provinces such as Ontario can penalise drivers who fail to slow down or move over, with fines and demerit points.
