You've just parked a lorry on the side of the road. What should you do just before dismounting from the cab?

• A. Make sure the radio is turned down
• B. Check the rear-view mirrors
• C. Make sure the hazard warning lights are on
• D. Check that all the windows are closed

Answer: (B)

Before getting out, you should check the rear-view mirrors. This lets you see if there’s any traffic alongside or approaching the vehicle and reveals any people or obstacles in your blind spots. Knowing this protects you from stepping into danger as you open the door. The other actions aren’t as safety-critical for the moment: turning the radio down isn’t about the exit itself, hazard lights are mainly for emergencies or breakdowns, and closing the windows isn’t required for a safe dismount. So checking the mirrors first is the best safeguard before you leave the cab.
