Hawaii Oversize Load Signs, Flags And Lights

Which Hawaii Sign Does The Published Rule Specify?

HAR 19-104-15(e) describes a wood or metal panel 6 feet by 1 foot, with 10-inch black letters on yellow and a 1¼-inch stroke, reading WIDE LOAD. It applies to each overwidth movement exceeding 12 feet.

Check the material and wording as well as the measurements. A flexible fabric banner labeled for a different jurisdiction should not be assumed equivalent to this published panel specification. If the permit office accepts an alternative, obtain instructions tied to the actual movement before relying on it.

Does The Same Sign Always Go On The Truck?

The rule says the sign is securely mounted at the carrier vehicle’s front or rear, or on the escort vehicle, as specified in the permit. It must be visible to approaching motorists without obstructing the driver’s view or warning/safety devices.

Review the district’s issued mounting instruction with both operators. A spare panel in the cab is not the same as a visible warning at the assigned position. Look for a clear view around mirrors, lamps and the load before tightening the mounts.

What Does The Hawaii Rule Say About Night Signs?

It specifies a reflective sign for movement at night. A separate projection provision discusses clearance lamps for certain long structural objects transported at night.

Keep the permitted hours separate from the equipment list. A reflective panel is an equipment feature, not approval for an after-dark trip. If port release or loading time changes, resolve the travel window with the responsible district rather than treating the original daylight plan as automatically transferable.

Where Are Hawaii Flags And Other Lamps Verified?

HDOT’s current administrative-rule index still links this older rule, whose relevant text carries a May 30, 1981 effective date. A complete statewide flag-size and beacon table was not established from the reviewed sections.

Use the issued special permit and ask the island district to confirm flags, extremity lights and escort equipment for the proposed route. This is a source limitation, not evidence that flags or amber lights are unnecessary. Check county authority separately wherever the trip leaves state-maintained highways; a state equipment summary does not answer all local movement conditions.

How Can RouteAll Help With This Movement?

Review the Hawaii permit’s named roads in RouteAll and compare the extraction with the original district-issued document. Resolve local access and equipment conditions with the responsible authority separately. RouteAll does not approve a panel material, assign the warning sign’s vehicle or authorize a nighttime movement. Get RouteAll For Permit Route Review.

Before You Roll

Confirm the district’s required sign position, panel details, travel window and unresolved flag/lamp conditions. Identify state and local road portions before departure. Keep the current permit and any clarification available to both carrier and escort operators.
