PrePass Says $692K in Savings. Your ISS Score Says Otherwise.

PrePass says a 250-truck fleet can recover roughly $692,250 in operational costs and 7,583 driver-hours a year just from weigh station bypasses. What their Mile Marker 2026 benchmarking report doesn't say: if your ISS score is too high, the bypass system reads your truck and waves you into the scale anyway. You paid for the subscription. You still pull in.

That gap between the advertised number and what a real small fleet actually captures is a compliance gap, not a technology gap.

The $692K Figure Is Conditional

The number assumes consistent bypass approvals across the fleet. Consistent bypass approvals assume the FMCSA's Inspection Selection System is already scoring your trucks low enough to qualify for the green light.

The ISS runs from 1 to 100 based on FMCSA safety data. High score means high inspection likelihood. The bypass system reads that score in real time. A fleet with a weak CSA record doesn't get to buy its way past the problem with a transponder subscription.

PrePass CEO Mark Doughty framed his report this way:

"Mile Marker 2026 shows why a national perspective is critical to measuring the full impact and benefits of weigh station bypass solutions. States have traditionally tracked their own results, but bringing those datasets together reveal larger trends and opportunities that are only visible when you step back and see the big picture."

That national perspective is exactly what hides the problem for small fleets. The benchmark averages across 40 states and more than 1.6 billion bypass events accumulated over nearly 30 years. A fleet running I-10 one week and I-90 the next is not operating in a national average. It's operating in two different enforcement corridors with different ISS thresholds, different staffing levels, and different approval rates on the same truck.

The Part PrePass Didn't Put in the Report

Bypass eligibility is a compliance output. It lives downstream of CSA scores, crash history, HOS violations, and driver qualification records. PrePass has published this directly in their own guidance material. They just didn't build it into the headline savings calculation.

There's a mechanic that catches small fleets off guard. The FMCSA needs a sufficient inspection sample to generate an ISS score at all. A fleet that doesn't get inspected often enough may end up without a score, and some states treat a missing score as a higher-risk flag. You can get pulled in precisely because your record is too thin, not because it's bad.

The way out of that trap is the same as the way into bypass eligibility: survive more inspections cleanly. Clean inspections improve your score over time. The bypass game is partly won by taking the inspections before you can start skipping them.

PrePass Has a Competitor, and the Competitor Has a Claim Worth Examining

PrePass describes itself as "North America's most utilized and technologically advanced weigh station bypass and toll payment platform" with more than 105,000 fleet subscribers. Drivewyze, now operating under Fleetworthy, counters that it "currently has the largest bypass network in the industry" by location count.

Both companies are publishing their own ROI reports. Fleetworthy launched a PreClear Savings Overview Report in October 2025, giving fleets visibility into bypass savings and missed opportunities.

"Both enhancements support the mission of providing customers with actionable insights to make better decisions," said Martin Murtland, VP of Product at Fleetworthy.

What neither company will tell you prominently is that the ROI comparison between them depends heavily on your specific lanes. Transponders are most reliable at the largest, highest-traffic weigh stations. Mobile covers more locations but works on different approval mechanics. A fleet that picks a vendor based on national network size and never checks whether that vendor covers their actual corridors is optimizing for a sales deck, not for their operation.

State Patchwork Is Not a Problem You Can Subscribe Out Of

ISS thresholds vary by state. A fleet with a solid record in one enforcement corridor can face regular pull-ins in another running the same equipment and the same drivers in the same week. PrePass's national benchmark smooths over this variation by design — that's what makes the headline numbers look so clean.

A fleet manager making vendor or route decisions based on national average bypass rates may be systematically underestimating pull-in exposure on specific lanes. The state patchwork is a planning and compliance problem before it's a vendor selection problem. Fleets need visibility into their per-state ISS exposure, not a cumulative savings estimate that assumes everything averages out.

It doesn't average out. Not for a 12-truck outfit running two corridors.

What You Have to Fix First

The practical sequence for a small fleet: get driver qualification files clean, reduce HOS and vehicle maintenance violations, build a clean inspection history. Then the technology starts paying what it promises.

The FMCSA data feeding your ISS score comes from the same documents that get messy under a DOT audit — CDL, medical card, MVR history, drug test results, Clearinghouse queries. These are the 18 required documents under 49 CFR Part 391. Let one lapse and you've got a compliance violation on your record. Stack a few and your ISS score climbs. Your ISS score climbs and your bypass approval rate drops. Your bypass approval rate drops and PrePass's $692K math stops applying to you.

FleetCollect's DQF Compliance Portal tracks those 18 documents and flags expiration dates before they become violations. That's not a bypass product — it's the infrastructure that makes a bypass product worth buying.

---

PrePass's math is accurate for the fleets that already deserve a green light. For everyone else, the transponder is decoration. The work that actually moves the ISS score is compliance work — unglamorous, administrative, and non-negotiable. Buy the technology after you've earned the right to use it.
