I was helping my little brother with his CDL permit test and was reading the manual again. One thing I noticed is that it said you must check the marker, turn, 4 way, tail, and BRAKE lights seperatly. So how do you check the brake lights? I dont know of any way to turn on the brake lamps only and have enough time to walk back and check them, wait maybeI do....a rubber tarp strap on the Trolley bar???
I remeber just walking around and making sure that the lights were working, ie brake lights turned on with marker lights.
Just curious
