New Mexico Frost Laws & Spring Thaw Limits

How New Mexico handles spring thaw

New Mexico has no frost laws. NMDOT posts no spring load limits, so your normal axle and gross weights hold year-round on Interstate, US, and state routes. The high country in the north can see hard freezes, but the state runs no seasonal weight program, and any weather or route condition on a heavy load rides on your NMDOT permit, not a frost order. Nothing seasonal to pull before you load.

Window, reduction, and where to check

• Season: No seasonal restrictions. NMDOT posts no spring load limits; the state's roadbeds do not thaw-weaken enough to warrant a frost program.
• Reduction: None.
• Interstates: Exempt from the seasonal reduction
• Find the current order: Nothing seasonal to check. Any weather or route condition on a heavy move comes through the NMDOT overweight permit, not a frost order. NMDOT commercial vehicle rules are the source for oversize and overweight limits.
• Overweight penalty: Not applicable; no seasonal limit exists. Standard New Mexico overweight fines apply to the normal size-and-weight limits (single axle 21,600 lb, tandem 34,320 lb).
