Oregon Adds Weigh Station Bypass by Phone App at 19 More Sites, From Ashland on I-5 to La Grande on I-84

By Big Rig Daily Staff

Truck drivers in Oregon can now use a phone app to bypass the scales at 19 more weigh station sites, according to the bypass service PrePass.

How it works

The PrePass Mobile App is now accepted for bypass at 19 sites in Oregon, deployed by the Oregon Department of Transportation, PrePass announced on Nov. 12. Vehicles that meet Oregon's safety and credential requirements may be cleared to bypass at highway speed.

At sites that take the app, it tells the truck driver whether the truck is cleared to bypass or must pull in, with both audio and on-screen text. PrePass says the app comes with its bypass subscription. The company says the change lets the state focus inspections on higher-risk vehicles.

The new sites

PrePass lists these Oregon locations, some covering both directions of travel:

• Ashland, Booth Ranch and Woodburn on I-5, both directions.
• Cascade Locks (eastbound), Emigrant Hill (westbound), La Grande (eastbound) and Wyeth (westbound) on I-84.
• Bend (northbound), Juniper Butte and Klamath Falls on U.S. 97.
• Cold Springs on Highway 730, Rocky Point on U.S. 30 and Umatilla (southbound) on I-82.

More bypass coverage

With the new Oregon sites, PrePass says it now offers weigh station bypass at hundreds of locations across North America. The company says using the mobile app along with a transponder, the small device mounted on a truck's windshield, gives a fleet access to more bypass locations, including sites that work only with the app.

The app also sends alerts for parking, safety, traffic and weather, according to PrePass. The company says open parking alerts are available in Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Ohio and Wisconsin.

Why it matters

Each bypass skips the slowdown, the line and the stop at the scale. PrePass says each successful bypass can save time and fuel and lower operating costs. Those are the company's claims.

A question for readers

Does weigh station bypass save real time on a trip, or does the truck still end up pulling in more often than not?
