ID-505
Aircraft Patrolled means police enforce speed limits on this highway from the air: aircraft time vehicles between pavement markings and radio ground units ahead to make the stop.
Information signs guide you to services and provide general directions.
Nothing special — just drive at legal speeds. The sign exists to remind you that no visible patrol car doesn't mean no enforcement.
Information and guide signs are usually green or blue rectangles. Green gives directions and distances; blue points to services like fuel, food, and lodging.
If it appears on the exam, it's as an information sign about speed enforcement methods — speeding can be ticketed even with no police vehicle in sight.
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. Learn the sign here, then put it into exam-style questions next to the right-of-way and graduated-licensing rules it shares the test with.
