Clearance lights are required for vehicles that are wider than:

Clearance lights are an important safety feature for wider vehicles, as they help to increase visibility and alert other road users to the dimensions of the vehicle. In Alberta, regulations specify that vehicles exceeding a width of 2.05 metres require clearance lights.

Choosing this specific width is significant because it aligns with safety standards aimed at reducing accidents caused by vehicles that might be less conspicuous due to their size. Clearance lights will typically be installed on the top corners of the vehicle to provide better illumination and to mark the vehicle's overall width, ensuring that drivers and pedestrians are aware of its presence.

Understanding this requirement is essential for commercial drivers, as it helps ensure compliance with safety regulations and promotes safe driving practices. Regularly checking vehicle dimensions and compliance with these rules is a key aspect of operating larger vehicles safely on the road.
