PrePass & Bypass Eligibility

Both Kentucky and Ohio participate in the PrePass electronic bypass program. Here's what drivers and fleet managers need to know for this corridor.

✅

How PrePass Works

A transponder mounted in the cab communicates with roadside sensors as you approach the station. If your safety record, weight, and credentials check out, you receive a green light and audio signal — you bypass without stopping. Red light means pull in.

⚠️

WIM Override

Weigh-in-motion sensors on the approach detect your axle weights before the transponder decision is issued. If you're over legal limits, you'll get a red light regardless of your PrePass account standing. PrePass bypasses weight enforcement — it doesn't override it.

🔴

Ports of Entry: No Bypass

Ports of Entry (like Berea/Madison County on I-75 NB) require all commercial vehicles to stop. PrePass does not apply at POE facilities — these are credential checkpoints, not weight-only stations. Budget time accordingly.

📋

Kentucky-Specific Rules

Kentucky requires all for-hire carriers to display KYTC authority or IRP registration. Even PrePass-eligible vehicles must have credentials accessible. KYTC may pull PrePass vehicles for random credential checks at any open station.

🏛️

Ohio-Specific Rules

Ohio enforces the federal bridge formula strictly. A load that's legal under 80,000 GVW may still be flagged if axle spacing creates a bridge formula violation. Ohio does not accept Kentucky overweight permits — separate ODOT permits required for oversize/overweight loads crossing into Ohio.

📱

Enroll in PrePass

Enrollment is through PrePass.com. Kentucky and Ohio are both member states. Annual fees vary by fleet size. Most owner-operators recover the cost in time savings within the first month of use on this corridor.

Weight Limits — Kentucky & Ohio

Federal limits apply to both states on interstate highways. State-specific limits and permit thresholds differ — key differences for this corridor are noted below.

Axle Configuration Federal Limit Kentucky (Interstate) Ohio (Interstate) Notes
Single Axle 20,000 lbs 20,000 lbs 20,000 lbs Standard; no variance
Tandem Axle (2-axle group) 34,000 lbs 34,000 lbs 34,000 lbs Standard; bridge formula may restrict further
Tridem Axle (3-axle group) 42,000 lbs 42,000 lbs 42,000 lbs Less common; verify bridge formula
Gross Vehicle Weight (5-axle combo) 80,000 lbs 80,000 lbs 80,000 lbs Standard 18-wheeler limit
Overweight Permit Threshold — >80,000 lbs — KYTC permit required >80,000 lbs — ODOT permit required ⚠️ Permits do NOT cross state lines
Spring Weight Restriction (KY) — Typically 6-axle limit reduced Feb–Apr N/A (Ohio has separate rules) KYTC spring breakup period — check KYTC.gov
Steer Axle 12,000 lbs 12,000 lbs 12,000 lbs Front axle; frequently checked at portable scales
📄

Overweight / Oversize Permits

Kentucky: Apply via KYTC's online permitting portal at transportation.ky.gov. Single-trip permits processed within 1 business day for standard loads; multi-trip and superload permits take 3–5 days and require route surveys.

Ohio: Apply via ODOT's e-permitting system at ohiogo.gov. Ohio does not accept Kentucky permits and vice versa. If your load crosses the state line, you need both.

Frequently Asked Questions

Common questions from drivers running the I-71/I-75 corridor through Kentucky and Ohio.

Do I have to stop at every weigh station on I-75 in Kentucky?

If you're operating a commercial vehicle over 10,000 lbs GVW, yes — you're required to pull into every open weigh station. The only legal exception is if you have an active PrePass transponder and receive a green bypass signal. Closed stations (lights off, no personnel) do not require a stop. The KYTC defines "open" as when the facility is illuminated and the OPEN sign is active.

Does my Kentucky overweight permit work in Ohio?

No. Kentucky and Ohio issue separate overweight/oversize permits and do not honor each other's authorizations. If you have a load exceeding 80,000 lbs GVW or legal dimension limits crossing from Kentucky into Ohio, you need a KYTC permit for the Kentucky portion and an ODOT permit for the Ohio portion. Apply to ODOT at ohiogo.gov — single-trip permits are often same-day.

What is the fine for skipping a weigh station in Kentucky?

Bypassing an open weigh station in Kentucky without PrePass authorization is a misdemeanor under KRS 189.222. Fines start around $200–$500 for first offenses but escalate sharply if the vehicle is also found to be overweight. KSP logs the event and the violation follows the carrier's safety record. Repeat bypass violations can result in FMCSA compliance reviews.

What happens at the Berea Port of Entry — why can't I bypass it with PrePass?

The Berea/Madison County facility on I-75 NB is a Port of Entry, not a standard weigh station. POEs are credential checkpoints — officers verify IRP registration, IFTA fuel tax credentials, operating authority (MC number), and may inspect safety equipment. PrePass only applies to weight-only stations. All commercial vehicles must stop at POEs regardless of transponder status. Budget 15–45 minutes depending on traffic volume when you arrive.

When are Kentucky spring weight restrictions in effect on I-75?

Kentucky typically posts spring weight restrictions (also called "spring breakup" restrictions) between February and April, depending on frost conditions. During this period, axle weight limits on some routes are reduced — though interstate highways like I-75 are generally less affected than state routes. Check KYTC's 511 system or transportation.ky.gov for active restriction maps before dispatching loads near the seasonal transition.

Is the Walton / Boone County station the only one near CVG Airport?

The Walton station on I-75 SB in Boone County is the primary fixed weigh station closest to Cincinnati/Northern Kentucky International Airport (CVG). However, KYTC and KSP also deploy mobile enforcement units on KY-18, US-42, and other arterials serving the CVG cargo logistics zone. If you're running freight from CVG on surface streets rather than the interstate, you may encounter portable scales, especially during peak air cargo season (October–December).

How do I get a PrePass transponder for this corridor?

Enroll at PrePass.com. You'll need your USDOT number, carrier information, and a credit card. Transponders are mailed within 5–7 business days. Both Kentucky and Ohio are participating PrePass states. PrePass also includes Drivewyze as an alternative bypass network — check which transponder or app is accepted at each station on your route, as not all stations accept both programs.
