Hitch mounted

Your patrol car is the sign stand.

Mount the sign on a vehicle hitch and the message goes wherever the vehicle goes: community events, changed traffic patterns, incident scenes and work zones. It folds back into the trunk when the job's done.

Frequently asked questions

18 or 24?

The 18 (30 × 20 inches, 29 lbs) suits short messages read at lower speeds. The 24 (60 × 28 inches, 43 lbs) carries more text at a larger size and folds in half for transport.

How long does setup take?

A couple of minutes, by one person. Plug in the battery pack and switch the sign on.

What can it display?

Up to six screens of custom text, chevrons and images: emergency alerts, travel times, detours, parking and event locations, weather updates, pedestrian crossings and more.

Can it show live conditions?

Yes. Messages can change on live inputs such as road or air temperature, water levels, weather alerts, timers or parking availability.

How long will it last?

More than a decade of year-round use: a welded aluminum enclosure, shatterproof Lexan and a graffiti-resistant powder coat.
