The Federal Motor Carrier Safety Administration (FMCSA) has begun enforcing current rules that prohibit carriers from placing extraneous information on placards and in placard holders. These devices are reserved for hazardous-materials information and officials say that advertisements, company logos and slogans, such as “Drive Safely,” can be distracting and confusing. Violators are subject to a civil penalty of at least $250 and not more than $27,500 per violation, and possible additional enforcement action by FMCSA.
