Federal and State Rules at a Glance

Warning flags are a federal requirement: 49 CFR 393.87 calls for red or fluorescent orange flags at least 18 inches square when a load extends more than 4 inches beyond the sides or more than 4 feet beyond the rear. Oversize load banners, pilot car signs, lights and travel times are set by each state and by your permit, so check every state on your route before you roll. Our oversize load permits by state guide covers the permit side.
