Alberta’s Traffic Safety Amendment Act, 2022 expands the circumstances in which drivers must slow down when passing a stopped vehicle displaying flashing warning lamps. The existing rule focused on stopped emergency vehicles and tow trucks; the amendment replaces that narrow category with a broader reference to vehicles displaying flashing lamps, subject to specific road, speed-limit and school-bus exceptions.
The change matters because it shifts compliance from identifying the type of stopped vehicle to recognizing its warning lights. It also creates a defined statutory meaning for “flashing lamp,” including strobe and 360-degree warning lights but excluding turn signals and required hazard-warning lamps.
At a Glance
What It Does
The bill amends section 115 of Alberta’s Traffic Safety Act so that the applicable speed restriction covers a vehicle passing a stopped vehicle with flashing lamps. On a highway with only two traffic lanes carrying traffic in opposite directions, the rule also applies to a driver approaching the stopped vehicle from the opposite direction.
Who It Affects
The rule directly affects drivers, roadside workers and operators of vehicles that use warning lamps while stopped on highways. It also affects enforcement agencies and organizations that operate service, utility, maintenance or other vehicles equipped with qualifying warning lights.
Why It Matters
The amendment broadens roadside protection without imposing the same rule in every circumstance. It excludes school buses from this particular restriction, preserves an exception for certain prescribed speed limits, and distinguishes warning lamps from ordinary turn signals and required hazard lights.

What This Bill Actually Does
The bill changes the speed rule in section 115(2)(t) of the Traffic Safety Act. A driver must not exceed 60 kilometres per hour, or the lower applicable speed limit, when passing a stopped vehicle with its flashing lamps operating.
The relevant speed is therefore the lower of 60 km/h and the maximum limit established under Alberta law, the federal Government Property Traffic Act or the federal National Parks Act.
The amendment covers a stopped vehicle on the same side of the highway as the driver. It also reaches a driver travelling in the opposite direction when the highway has only two traffic lanes carrying traffic in opposite directions.
That road-design limitation is important: the text does not extend the opposite-direction rule to divided highways or roads with more than two opposing traffic lanes.The bill adds a definition of “flashing lamp.” It includes stationary or rotating flashing lamps, strobe lamps and 360-degree warning lamps. It does not include a turn signal or a vehicle hazard-warning lamp when that lamp is required under the regulations.
The definition gives drivers and enforcement officers a statutory basis for distinguishing dedicated warning equipment from ordinary signalling equipment.The revised subsection 115(4) creates two exceptions. The restriction does not apply where a speed limit has been prescribed under section 108(1)(g), or when the stopped vehicle is a school bus.
The bill also reworks the opening of section 115 by expressly defining “school bus” for that section as a vehicle displaying the words “school bus.” It comes into force on proclamation, leaving the operative date to be set separately.
The Five Things You Need to Know
The operative threshold remains 60 km/h or the lower maximum speed limit applicable to the highway; the bill does not create a universal 60 km/h permission where a lower limit applies.
The expanded rule applies when a driver travels on the same side as a stopped vehicle with flashing lamps, and in the opposite direction only on a highway with two traffic lanes carrying traffic in opposite directions.
“Flashing lamp” includes stationary or rotating flashing lamps, strobe lamps and 360-degree warning lamps, but excludes a turn signal and a vehicle hazard-warning lamp required under regulations.
The amended restriction does not apply where a speed limit is prescribed under section 108(1)(g).
A stopped school bus is excluded from the amended subsection 115(2)(t) restriction, and the bill defines a school bus for section 115 as a vehicle displaying the words “school bus.”.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Amends the Traffic Safety Act
Section 1 identifies the statute being changed: Alberta’s Traffic Safety Act, chapter T-6 of the Revised Statutes of Alberta 2000. It establishes that the remaining provisions operate as amendments to that Act rather than as a standalone traffic regime.
Defines qualifying flashing lamps
The bill adds “flashing lamp” to the Act’s definitions. The term captures several forms of dedicated warning equipment, including stationary or rotating lamps, strobe lamps and 360-degree warning lamps.
The exclusion for turn signals and regulated vehicle hazard-warning lamps prevents ordinary signalling equipment from triggering the roadside slowing rule merely because it flashes. The definition leaves the practical question of whether a particular lamp qualifies tied to the equipment and its use, rather than simply to whether any light on the vehicle is blinking.
Adds a section-specific school-bus definition
The bill renumbers the existing subsection 115(1) as subsection 115(1.1) and inserts a new subsection 115(1). For section 115, “school bus” means a vehicle displaying the words “school bus.”
This is a targeted definition used by the exemption later in the section. It does not, on its face, create a general definition of school bus for every provision of the Traffic Safety Act.
Expands the stopped-vehicle speed restriction
The amendment replaces the former reference to a stopped emergency vehicle or tow truck with a stopped vehicle displaying flashing lamps. The same-side rule therefore applies to a broader set of roadside vehicles, while the opposite-direction rule applies when the road has only two traffic lanes carrying traffic in opposite directions.
The bill also changes the related wording from “emergency vehicle or tow truck” to “vehicle,” aligning the operative language with the broader flashing-lamp test. Drivers must still comply with the lower applicable speed ceiling rather than automatically travelling at 60 km/h.
Preserves two exceptions
The revised subsection 115(4) removes the former lane-separation exception and replaces it with two exclusions. The subsection 115(2)(t) restriction does not apply where a speed limit is prescribed under section 108(1)(g), or when the stopped vehicle is a school bus.
The change is significant for divided or multilane roads because the former text expressly excused a driver who had at least one lane between the vehicle and a stopped emergency vehicle or tow truck. The enacted wording instead defines coverage through the direction of travel and the number of opposing traffic lanes, while separately excluding the listed situations.
Sets proclamation as the start mechanism
The Act comes into force on proclamation. The amendment therefore does not make its traffic rules operative solely by receiving assent; a proclamation determines when drivers, vehicle operators and enforcement agencies must apply the revised wording.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Roadside service and maintenance crews using qualifying warning lamps benefit from a rule that covers more than the previously listed emergency vehicles and tow trucks.
- Drivers approaching stopped vehicles on two-lane, bidirectional highways receive a clearer statutory signal to reduce speed when dedicated warning lamps are operating.
- Police and traffic-enforcement agencies gain a broader statutory category for addressing speed near stopped warning-lamp-equipped vehicles, although they must assess the lamp and road configuration.
- Operators of utility, transportation, construction and other service vehicles that use dedicated warning systems may receive greater protection while working on or beside highways.
Who Bears the Cost
- Drivers face additional speed-reduction obligations when passing qualifying stopped vehicles, including vehicles outside the traditional emergency-response and towing categories.
- Fleets that stop on highways may need to confirm that their warning equipment qualifies as a “flashing lamp” and that drivers use it consistently if they expect the rule to protect roadside operations.
- Employers and fleet managers may need to update driver training, roadside procedures and compliance materials to reflect the broader vehicle category and the opposite-direction rule on two-lane highways.
- Police, courts and enforcement agencies may bear interpretive and evidentiary costs in determining whether a stopped vehicle’s lamp falls within the statutory definition and whether the highway satisfies the specified lane configuration.
Key Issues
The Core Tension
The bill seeks to protect a wider range of roadside workers and stopped vehicles without imposing the same speed restriction across every highway situation. Its solution depends on line-drawing—between qualifying and excluded lamps, two-lane and multilane roads, and covered vehicles and school buses—which improves targeting but leaves more room for factual disputes and uneven driver understanding.
The bill broadens the protected class of stopped vehicles but does not define every vehicle that may use a qualifying warning lamp. That approach makes the rule technologically flexible, yet it can shift disputes toward the lamp’s design, regulatory status and operating condition.
A flashing light alone is not enough if it is merely a turn signal or a required hazard-warning lamp excluded by the definition.
The road-configuration rules also require drivers and enforcement officers to distinguish between same-direction and opposite-direction travel. The amendment is more expansive on a two-lane bidirectional highway than on a divided or multilane road, while the replacement of the former lane-separation exception changes how protection operates where lanes separate traffic.
The school-bus exclusion creates a further boundary: a vehicle prominently identified as a school bus is outside this particular restriction, even though other traffic-safety rules may apply.
Finally, the interaction with section 108(1)(g) leaves an important operational question in the existing speed-limit framework. The bill preserves an exception for prescribed speed limits rather than explaining how that provision should be applied in every roadside setting.
Compliance programs will need to account for the exact road, vehicle, lamp and speed-limit circumstances instead of treating the amendment as a blanket slow-down rule.
