Kentucky Frost Laws & Spring Thaw Limits

How Kentucky handles spring thaw

Kentucky runs no statewide spring thaw program. Winters can freeze the ground, but the Kentucky Transportation Cabinet (KYTC) issues no seasonal frost order, so standard limits hold year-round (KRS 189.222; 603 KAR 5:066): 80,000 lb gross, 20,000 lb single axle. The catch is local. Counties and cities post their own bridge and road weight limits, and a signed 'X-ton' cap is the legal limit there even with no state order. Read the signs.

Window, reduction, and where to check

• Season: No seasonal restrictions statewide. Kentucky declares no annual spring thaw order; standard limits apply the same year-round, though locally posted road and bridge caps can appear in any season.
• Reduction: None statewide. No seasonal percentage cut or spring tonnage order from KYTC. Only local governments post their own year-round 'X-ton' bridge and road limits, which are hard caps on those roads.
• Interstates: Exempt from the seasonal reduction
• Find the current order: KYTC posts no seasonal load-restriction map because there's no statewide frost program. Obey posted county and city bridge/road weight-limit signs, which run year-round, and confirm heavy or oversize movements with the Kentucky Transportation Cabinet (KYTC) permit office before you roll.
• Overweight penalty: No seasonal-overweight fine, because there's no state seasonal limit. Plain overweight draws Kentucky's standard penalty of 2 cents per pound of excess load, with a $100 to $500 fine once the excess tops 5,000 lb (weight rules under KRS 189.222; penalties under KRS 189.990).
