Vehicles wider than what width require clearance lights?

Vehicles wider than what width require clearance lights?

• A. 1.55m
• B. 2.05m
• C. 1.20m
• D. 3.05m

Answer: (B)

Clearance lights are there to show other drivers how wide a vehicle is, especially in dim light or poor visibility. In Alberta, the rule is that vehicles wider than 2.05 meters must have these lights. That width, about 80 inches, is used because it marks out a vehicle size that is noticeably wider than standard cars, helping maintain safety on the road. The other options are outside the practical threshold: 1.55 meters and 1.20 meters are typical widths for ordinary vehicles and don’t require clearance lights, while 3.05 meters is far wider than normal road vehicles and would be governed by other regulations and equipment. So the width that triggers clearance lights is 2.05 meters.
