Signs, flags and lights
Most states require
- An “OVERSIZE LOAD” banner on the front of the truck and the rear of the load.
- Red or fluorescent orange warning flags at each corner and at the widest points of the load.
- Amber warning lights or clearance lights when moving at night, where night travel is allowed.
Arkansas specifics
- Banner size, flag size and light rules for Arkansas are listed on your permit.
- We include them in your permit notes so your driver has them before the trip.
Rules change. Limits and requirements are set by ARDOT and can change. We confirm the current rules for your exact load before filing.
