PrePass Bypass Saves 7 Minutes and $10.65 Per Event, New Index Shows
National benchmark built from 1.6 billion bypass events puts hard numbers on weigh-station bypass ROI — and makes the case that schedule consistency beats raw speed.
How much time and money does a single weigh-station bypass actually save?
Seven minutes of drive time, half a gallon of fuel, and $10.65 in operational costs, according to PrePass Mile Marker 2026: The National Bypass Impact Index released May 4. The benchmark draws from more than 1.6 billion authenticated bypass events across 40 states from 1997 through October 2025.
Cumulative totals over that 28-year span: 135,319,941 driver hours saved, 579,944,286 gallons of fuel saved, and $12,352,813,292 in operational cost savings. The per-bypass average is the first national benchmark that puts a consistent dollar figure on what bypass returns to a fleet.
What a 150-truck fleet saves in a year
A 150-truck operation completing 150 bypasses in a single workday would bank 17.5 hours of drive time, 75 gallons of fuel, and roughly $1,598 in savings, according to the Mile Marker 2026 figures. Held steady across 250 working days, that single-day return scales to 4,375 hours, 18,750 gallons, and about $399,500 in annual savings.
The index frames bypass as a reliability tool, not a speed tool. A truck that runs the same timetable every trip is worth more to a fleet than one that runs fast on its good days, PrePass argues. Schedule swings — arrival times that vary 20 minutes in either direction — force rework: re-sequencing loads, re-contacting shippers, re-calculating driver hours, re-allocating equipment. None of that labor is recovered by faster trips on good days.
How bypass eligibility works
Bypass is earned through FMCSA safety data and ISS scores. Mandatory, random, and periodic inspections remain in effect for all carriers. Enforcement attention is directed toward higher-risk vehicles, and carriers with strong compliance records earn more bypass opportunities. The PrePass system uses transponders mounted in the cab to communicate with roadside readers at weigh stations; qualified trucks receive a green light and continue at highway speed.
Why consistency matters more than pace in tight markets
Inconsistency is the cost center most fleets still aren't tracking, according to the Mile Marker 2026 report. In a tight market, consistency separates fleet value from fleet activity. A fleet can run at a competitive pace and still lose value when arrival times swing. That variation breaks plans, erodes margins, and strains customer relationships.
Reliability combines in a fleet's favor; schedule swings combine against it. The fleets that come out ahead are the ones whose operations hold up under stress, not the ones that shave seconds off a good day, PrePass states.
What the benchmark means for small fleets
The 7-minute, $10.65 per-bypass figure gives small fleets and owner-operators a concrete number to plug into their own route math. A truck running 200 bypasses a year would save 1,400 minutes — 23.3 hours — and $2,130 in operational costs, based on the national average. A five-truck fleet at the same bypass rate would save 116.5 hours and $10,650 annually.
The index does not break out bypass savings by state, weight class, or commodity type. The 7-minute and $10.65 figures are national averages across all bypass events in the dataset. Actual per-bypass savings will vary based on route, time of day, and weigh-station queue length.
PrePass is North America's most utilized weigh-station bypass and toll payment platform, with more than 105,000 fleets subscribing over 750,000 commercial vehicles to PrePass services. The Mile Marker 2026 index is available at PrePass.com.
