Yeah.... they're supposed to be. But in the last 5 years, none of my trailers have had a lighted plate and I've never been hassled by the man. Hell, I even got away with blazin' down I-80 doing 75+ coming out of Sacremento. I was wondering why people kept looking at me funny as I passed them or they passed me. Wasn't until I was out of CA before I found out that they have a trailer speed limit of 55. :homer::flipoff2:Does Missouri require a lighted trailer plate??
actually I think WA does to (I know they do for vehicles) but mine never has and I've been followed/passed stater's a couple of times but no one has ever made and issue of it.
Heck, my plates riveted/wrapped around my fender. Has never seemed to me an issue.
