Any CDL instructors out there? How does one test the brake lights during the CDL Class A exam please? Thanks, The Shadow.
Simple: You have someone tell you if the lights work while you depress the brake pedal. Unless you have a giant mirror to back your truck up to, that is.
press the brake pedal and run rally really fast.. LOL... some trucks have trolley valves on them so use that, if your truck dont have one if someone is around ask them to help, or if your by yourself you can find something to press the pedal down or maybe a mirror or something reflective.
I had a guy ask me to get out & see if his directional signal was working. I said "yes they are, no they're not. Yes they are, no they're not." Thanks, I'll be here all week.
