Roadside worker safety

Help protect roadside workers on busy Alberta roadways.

Roadside worker safety rules

When driving in the closest lane to any stopped roadside vehicle with flashing lights activated, such as police, ambulances, fire trucks, tow trucks and maintenance trucks, including those in construction zones:

  • you must move over to the far lane to give workers extra space
  • if you can’t safely move over, you must slow to at least 60 km/h, or the posted speed limit (whichever is lower)

Driving reminders

  • Construction or maintenance zones will have roadway signs in advance to warn motorists that road work is being done. Even if there are no signs reminding motorists that fines will be doubled, your fine could be doubled if workers are present.
  • Flashing lights from emergency response vehicles and other roadside workers will warn you of a problem ahead.
  • When approaching an emergency or a construction/maintenance situation, use caution and slow down.
  • Move over to the far lane whenever possible.
  • Always be aware that vehicles ahead of you may stop suddenly.
  • Obey directions by flag people or emergency workers.
  • Avoid watching the emergency and keep focused on driving.
  • Always leave plenty of space between your vehicle and other people and equipment parked or being operated at these locations.

The regulatory changes introduced in September 2023 strengthen safety measures to better protect all first responders and roadside workers on Alberta’s highways. The new rules require motorists to slow down to 60 km/hour or the posted speed limit (whichever is lower) when passing stopped vehicles with flashing lights. 

  • The new safety rules give snowplow operators and roadside maintenance teams the same protection as first responders, tow truck operators, and construction crews.
  • There regulatory changes stemmed from recommendations heard from the public and stakeholders during the roadside worker safety engagement held in spring 2021.
