Company name — Your legal name or single trade name, exactly as listed on your MCS-150. If another name appears on the truck, yours must be marked "operated by."

Federal rule (49 CFR 390.21): markings go on both sides of the power unit, in letters that contrast sharply with the background and are legible from 50 feet in daylight. Paint or vinyl decals both count. Kentucky no longer requires the KYU number to be displayed on the truck.
