New Mexico Truck Mud Flap Law
New Mexico has no specific mud-flap or splash-guard law. Chapter 66 sets no flap width and no ground-clearance number, so nothing dimensional exists for a DPS officer to measure (New Mexico sits on the NTEA no-requirement list). You won't catch a flap-specific ticket in-state. That protection stops at the line: Arizona's 8-inch rule, Utah's half-diameter rule, and Colorado's guards all bind your truck once you cross. Run full-tread flaps close to the road and you're covered everywhere.
A detail here is flagged medium confidence — confirm with the state statute before you rely on it.
