Question on trailer lights/blinkers

You do not need a blinker on the side of a trailer. You just need one at the rear of the trailer and truck with the one on the front of the truck. 3 total is all that is needed.

 

Your correct in the fact that this light in question is not required by law, however any and all exterior lights on the vehicles must be in proper working order. I have experienced as a former "Chickin Hauler" and no doughty you may have over heard other Chickin Haulers complain about the fact that some DOT officers take pleasure in finding these lights that are out.

However, TruckerDan mentioned that the light did come on when he turned the signal on therefore I don't think a DOT officer would fault him just because it didn't blink. I think at the most the DOT officer might point it out or question it and I recommend just off handedly saying, yeah all these trailer of year model do that, and be done with it.

 

depends on the trl if its a 53 ft trl it does need a turn on the side and the if its on there it has to work is not the fed dot law but there are several states that have that

Yea bro, we know that. Its just getting the DOT cops to actually read the laws.

 

Print that little tidbit off keep it in the truck and when its questioned whip it out and show it to them. Right there in black and white. If they can't understand that they need to find a new profession
