Nebraska Truck Mud Flap Law

What Nebraska makes you run

Nebraska requires a splash device, not a specific size. Every truck and semitrailer must carry fenders, covers, flaps or splash aprons unless the body itself blocks spray and splash to the rear (Neb. Rev. Stat. 60-6,283). No inch number, no width formula. So a trooper checks whether your rear tires are effectively covered, not a tape measure. A missing flap is a correctable equipment infraction, not out-of-service, and CVSA's 2025 note says rubber touching a tire isn't OOS either.

Coverage and clearance

• Required: Yes
• Coverage: No stated width. The device only has to effectively minimize spray or splash of water or mud to the rear; the statute names no full-tread-width figure.
• Ground clearance: No set clearance number. The statute requires an effective splash device but gives no inch figure. Fenders, covers, flaps or splash aprons must minimize spray or splash to the rear (Neb. Rev. Stat. 60-6,283).
• Fine: Traffic infraction (equipment), waiverable and low-dollar. Nebraska's fine schedule lists the splash-guard offense at $25 plus court costs; first-offense traffic infractions cap at $100 (Neb. Rev. Stat. 60-6,283).
