RB-75
Truck Inspection Station signs direct commercial vehicles to a weigh scale / inspection facility ahead. When the station is open, trucks over the posted weight must pull in.
Regulatory signs control how you may use the road — they must be obeyed.
Commercial drivers: follow the signs into the station when signals indicate it's open. Passenger-car drivers: no action needed, but expect trucks merging out of the station ahead.
Regulatory signs are usually white rectangles or squares with black or red markings. A few have special shapes: a red octagon means Stop and a red-and-white downward triangle means Yield. A red circle with a slash means something is prohibited.
The knowledge test occasionally checks that you know inspection stations are mandatory for the vehicles they apply to — skipping an open scale is an offence for truck drivers.
Road signs are one of the five areas the 30-question Alberta Class 7 knowledge test covers, and the largest block in our mock exam at 8 questions. Once the signs feel automatic, work through the full set of Class 7 practice questions, which also covers rules of the road, right-of-way, safe driving, and penalties.
