Landscaping truck lettering: C-27 license, USDOT with a trailer, and what to put on the doors

Two rules, one door

CSLB: business name and license number, 3/4 inch minimum, on commercially registered vehicles used in the business. FMCSA and California DMV: USDOT and CA number once the combination is rated 10,001 lbs or more. A half-ton pickup with a 16 foot tandem trailer is over.

The layout that works

Company name biggest, then 'CSLB Lic# 1098765', then USDOT and CA on the next lines. Four lines fit a pickup door at 1.5 inch numbers. Add the phone number if you want the neighbors calling.

Green on white

Landscapers love green lettering. It reads fine on white; on a green or dark truck it disappears and fails the contrast rule. Our designer warns you.
