The regulation requires the light to come on if there is a malfunction and the system stores the malfunction . I can't find anything stating the light on is a violation .
There is also a light on my tractor dashboard for trailer ABS that comes on with the ABS light on the trailer .
We have one trailer with an ABS light that will come on when the trailer air bags are deflated . When the bags are inflated it will not go out until the tractor is shut down and restarted .
Trailer ABS out a citable offense?

That's all good until caught doing it. I have had three different driver's try that with the low air device. That's a fun day watching the driver squirm when questioned about it. "But....But.....But." -

I got a warning from a DOT officer for not have the letters "A.B.S." printed on my ABS lite. There was nothing wrong w/the light working correctly.

Must have missed that regulation! -
I did miss that regulation. It's in the 121 Brake standard. Here it is:
(S5.2.3.3)(b)(3) The letters ABS shall be permanently molded, stamped, or otherwise marked or labeled in letters not less than 10 mm (0.4 inches) high on the lamp lens or its housing to identify the function of the lamp. Alternatively, the letters ABS may be painted on the trailer body or dolly or a plaque with the letters ABS may be affixed to the trailer body or converter dolly; the letters ABS shall be not less than 25 mm (1 inch) high. A portion of one of the letters in the alternative identification shall be not more than 150 mm (5.9 inches) from the edge of the lamp lens.free2fly973, stranger, JustSonny and 1 other person Thank this. -
