Hawaii pilot car regulations

Certification: not required. Hawaii's oversize permit rule (HAR 19-104, from 1981) sets no escort driver certification. The permit holder supplies escorts when the permit or law calls for them, generally one per load.

From Hawaii's own rules and pages, checked 2026-10-24. Rules change: the state's page is the last word.

Escort vehicle

A passenger car or a 2-axle truck rated at no more than 20,000 lb gross, with a clear view to the front and rear. Low beam headlights on. Keep 200 to 600 feet from the load depending on speed.Source

Lights

At least one rotating or oscillating amber light on top of the cab, bright enough to be seen at 500 feet in normal sunlight.

Flags

When the permit calls for a flagman: red flag 24 x 24 inches on a 3-foot staff, and a bright orange safety vest.

Other equipment

Two-way radio in the escort and the truck, with continuous contact.
