The agency said it is taking this action as a result of a requirement issued by DOT's Research and Special Programs Administration (RSPA) that prohibits the use of placards for anything but hazardous materials information. That means advertisement messages and even safety slogans such as "Drive Safely" will be banned from trailer placards.
The prohibition subjects violators to a civil penalty of at least $250 and not more than $27,500 per violation, said FMCSA.
