ROH §41-29.3
When business signs on vehicles are allowed
Read the official text at honolulu.gov ↗This section says businesses can put their name or logo on a vehicle or trailer, as long as the vehicle is registered to the business and the sign is not a safety hazard. The vehicle must be used mainly for the business's regular work, not just for advertising. Parking it in a spot to attract attention as a billboard is not allowed.

The ordinance, as written (Honolulu County) — Business identification permitted
A copy, taken August 22, 2026. The version published by Honolulu is the one that governs, and it may have changed since. Check it before relying on anything here.
Nothing in this article shall prohibit the identification of a business enterprise, as defined in § 41-29.1 , upon a vehicle or trailer, or both, provided however:
(1) The vehicle is registered in the name of the business entity; and provided that such identification will not constitute a hazard to motorists or will impair the operation of the vehicle; and
(2) The vehicle or trailer, or both, is primarily used for the purpose of and in the ordinary conduct of the business of the owner or lessee of the vehicle. The vehicle or trailer, or both, however, cannot be used only for the purpose of advertising. Any subterfuge of the owner or lessee of the vehicle or trailer to promote the sale of its product, material, supplies, or services by situating its vehicle or trailer, or both, in a strategic location on any highway, street or private property calculated to attract the attention of motorists or pedestrians, or both, to its advertisement in circumvention of State and county billboard advertising or sign laws shall not be permitted under this section.
