Avoiding fines at Kentucky weigh stations comes down to preparation, compliance, and understanding how Kentucky enforces commercial vehicle regulations. The Kentucky State Police (KSP) and Kentucky Transportation Cabinet (KYTC) monitor weight, credentials, and safety requirements closely—so even small mistakes can lead to citations, delays, or out-of-service orders. Below is a complete guide to help truckers stay compliant and avoid costly penalties.

1. Know When You Must Stop at a Kentucky Weigh Station

All commercial motor vehicles (CMVs) over 10,000 lbs. GVWR engaged in interstate or intrastate commerce must stop at open weigh stations.
You must also stop if:

  • You’re hauling an oversize or overweight load

  • You have a temporary trip/fuel permit

  • You’re flagged for inspection (random or targeted)

Skipping a weigh station can trigger significant fines and an enforcement stop.

2. Ensure Your KYU Number Is Active and Up to Date

Kentucky requires a KYU number for carriers operating vehicles over 59,999 lbs.
To avoid fines:

  • Make sure the KYU account is active

  • File quarterly KYU weight-distance taxes on time

  • Keep copies of filed reports in the cab

Inactive or delinquent KYU accounts are one of the most common violations.

3. Keep IFTA and IRP Credentials in Order

Before entering any weigh station:

  • Your IFTA license and decals must be valid

  • Your IRP registration must match the vehicle

  • Trip/fuel permits must be readily available

Missing or expired credentials can lead to on-the-spot fines and shutdowns.

4. Verify Your Axle Weights Before Entering Kentucky

Kentucky enforces federal weight standards, including:

  • 80,000 lb. gross weight limit

  • 20,000 lb. per single axle

  • 34,000 lb. on tandems (with proper spacing)

  • Bridge formula compliance

Use your onboard scale or CAT scale to verify weight before arrival.
Being overweight—even by a small margin—can lead to immediate citations.

5. Double-Check Permit Accuracy for Oversize/Overweight Loads

If your load requires a permit, review:

  • Dimensions (height, width, length, weight)

  • Route restrictions

  • Curfews and travel time limits

  • Escort requirements

  • Holiday and weekend restrictions

Incorrect permit info = fines + required re-permitting before continuing.

6. Ensure Lights, Brakes, and Safety Equipment Meet DOT Standards

Weigh stations can conduct Level I, II, or III inspections.
To avoid safety-related fines:

  • Check brake adjustment

  • Inspect lights and reflectors

  • Confirm tire tread and condition

  • Secure all cargo properly

  • Ensure fire extinguisher and triangles are present

A simple burned-out light can turn into a long inspection delay.

7. Keep All Required Documents Readily Available

Drivers should have:

  • CDL and medical card

  • Registration and proof of insurance

  • IFTA/IRP paperwork

  • Bill of lading

  • Oversize/overweight permits

  • Lease agreements, if applicable

Missing documents often results in citations or extended delays.

8. Follow Weigh Station Signs and Signals Carefully

Common mistakes include:

  • Entering the wrong lane

  • Ignoring bypass or inspection instructions

  • Failing to stop at instructed points

Even minor missteps can trigger enforcement action.

9. Maintain Professional Conduct

Inspectors take note of:

  • Driver attitude

  • Communication

  • Cooperation

Being polite and prepared reduces the chances of extended inspections.

10. Keep Your ELD and Logbooks Error-Free

Kentucky reviews Hours-of-Service (HOS) compliance.
Avoid violations by ensuring:

  • Logs are current to the last change of duty

  • No missing logs

  • No unassigned driving time

  • ELD is functioning properly

HOS violations are among the most expensive and time-consuming issues.

11. Watch for Random Mobile Weigh Inspections

Kentucky uses:

  • Portable scales

  • KSP mobile inspection units

  • Surprise roadblock inspections

Always stay in compliance—not just at fixed weigh stations.

Final Tips to Avoid Fines

  • Weigh your truck before entering Kentucky

  • Keep permits and documents where you can grab them instantly

  • Maintain your equipment daily

  • Avoid rushing—mistakes cause violations

  • Stay current on KYU, IFTA, and IRP obligations
