3, 2002 displaying an ICC number on a commercial motor vehicle
won't be enough, the Federal Motor Carrier Safety Administration
revised rules now require "for-hire" motor carriers
operating in interstate commerce to display the following information:
"the legal name or a single trade name of the motor carrier
(as listed on Form MCS-150); and the motor carrier ID number
issued by FMCSA, to be preceded by the letters "USDOT."
the number must be displayed on both sides of the power unit.
FMCSA also says the letters must contrast sharply in color with
the background on which they are placed; they should be readily
legible during daylight hours from a distance of 50 feet while
the vehicle is stationary; and they should be kept and maintained
in a manner that retains legibility.
