In a pre-trip inspection, what should you verify about safety-critical components before operation?

• A. They are safety-critical components before operation
• B. They are not safety-critical and may be ignored
• C. They do not require maintenance
• D. They are optional to inspect

Answer: (A)

Before you operate, you verify that safety-critical components are functioning properly. These parts are essential for control and stopping, so the pre-trip inspection focuses on making sure they’re present, secure, undamaged, and working as they should. You’d check brakes (service and parking), steering for any play or leaks, suspension and frame integrity, tires and wheels (tread, inflation, cuts, damage), lights and reflectors, signals, horn, wipers, mirrors and their adjustment, seat belts, and, if pulling a trailer, the coupling and safety chains. Also look for any exhaust or fuel system leaks and ensure any required emergency equipment is on board. If something isn’t right, it must be fixed before you drive. Ignoring these parts or treating maintenance as optional isn’t acceptable because safety-critical systems directly affect your ability to control the vehicle and stop safely, and Alberta requires these checks as part of the pre-trip.
