New Hampshire Oversize Load Signs, Flags And Lights

What Does New Hampshire Specify For Banner Construction?

Tra 304.15(d) calls for black lettering on yellow and durable material unaffected by moisture. The front and rear displays must not obscure the license plate. Paragraph (e) requires covering, removing or otherwise restricting the view of the signs when not being used for an oversize move.

Inspect a flexible banner for damage and curling after installation. A nominal size written on an invoice does not explain whether the warning remains readable in service. Plan where the signs will be stored or covered after the load is delivered.

How Many Flags Should Mark The Actual Load?

Tra 304.15 requires flags at least 18 inches square at longitudinal and lateral extremities. Overwidth loads use at least four and up to six flags at the widest points and corners, without increasing overall width; overlength and front or rear overhang cases have a four-corner instruction.

Use the shape rather than a fixed four-flag habit. A wider middle section may require a different mounting plan from a rectangular crate. Secure the flags as the rule describes, rather than allowing a loose flag to migrate behind the load.

What Must Be Visible From A Thousand Feet?

Paragraph (f) requires an operating top-mounted flashing or strobe amber lamp visible 1,000 feet in all directions on the hauling vehicle. That visibility instruction belongs to the truck check, not just to a pilot car that happens to be nearby.

Check whether the loaded cargo, equipment or sign blocks the lamp from a particular approach. Resolve that with the carrier before departure. If the installation changes after loading, repeat the visibility check rather than relying on the earlier unloaded inspection.

Does A Pilot Car Replace These Truck Warnings?

No replacement is established by the load-marking paragraph. The escort provisions elsewhere in Tra 304 need their own review. Do not assume an escort’s warning display cures missing flags or an obscured rear banner on the hauling unit.

New Hampshire’s state permit also does not authorize every local-road leg. At the trip meeting, distinguish equipment checks from route permissions and identify any municipal condition still to be resolved. The state’s driver checklist is a useful prompt to review the complete packet before moving.

How Can RouteAll Help Prepare This State Leg?

Import the issued New Hampshire permit into RouteAll, review the extracted roads against the document and share the reviewed route with the crew. Use the permit packet to check marking conditions separately. RouteAll does not inspect warning equipment or certify compliance; a route shown in the app does not approve signs, flags or lamps.

Before You Roll

Check the weather-resistant sign faces, unobscured plate, mounted flags and all-direction cab-light visibility, then review any additional permit or local condition.
