For carriers with good Compliance Safety Accountability scores, and consequently with no pressing need to log clean inspections, any weigh station bypassing service âwill offer an immediate reduction in inspections,â says Brian Mofford, a representative of bypass service Drivewyze.
That scenario has become increasingly common, and 2012 was no exception. PrePass coverage across the nation got a boost with the addition of Texas and Kentucky weigh stations to its now-31-state system. The majority of the contiguous states now are covered by the service.

Drivewyze, a competing service, launched last fall and quickly is coming available at fixed sites; at press time, it was available in 15 total states, with âa state every monthâ planned for the year, says Mofford. Drivewyze also will become a standard feature of officersâ mobile stations to allow some bypassing in those areas. Find a list of Drivewyze states via Drivewyze.com; rates are $12.99 per month per truck for interstate haulers â volume pricing is negotiable for fleets â and the system operates via an app on operatorsâ smartphones.
Carriersâ Inspection Selection System scores drive the bypass rate. As a general rule, good CSA scores mean a good ISS score. A carrier can find its ISS score by logging into its carrier profile with a U.S. Department of Transportation-issued PIN.
With Drivewyze, carriers with ISS scores below 75 âwill be bypassed 98 percent of the time,â Mofford says. As ISS scores move to 75 and above, the bypass rate gets smaller.
âWe look at it as a way for those with good inspections to save time and money without having to go on the mainline,â he adds. âFifty percent of the time, the others can avoid it tooâ if they want. Many owner-operators and small carriers will register ISS scores in the 50-75 range since the ISS algorithm prioritizes carriers with little to no data in the system for âoptionalâ inspection.
PrePass works in a similar fashion, with below-90 ISS-score carriers and some state exceptions seeing a 95 percent bypass rate. As scores move higher, pull-in rates follow.
California, ranking second in Overdriveâs rating of inspection intensity, is a notable exception. If your ISS score gets to 75, you may as well turn off the PrePass transponder. The system there pulls in all trucks at 75 or above.
