Green Light Preclearance Program

A Free Way to Save!

Green Light is a "preclearance" system that verifies truck size, weight, registration and safety records as it drives on the freeway. Green Light allows compliant commercial motor vehicles to bypass Oregon automated weigh stations. Bypassing a weigh station saves time and money. It is safer and good for the environment. Enjoy all these benefits at no cost to the motor carrier.
 
The Oregon Green Light Program is interoperable with other preclearance programs in the country.

Carrying both transponders will likely cause problems because each transponder simultaneously emits its identifying signal. Even if you are traveling in Oregon with your Green Light transponder mounted correctly and your PrePass transponder stored in the glove box, there is still a good chance the system will detect the PrePass transponder signal first and spoil the chance to preclear the weigh station.

For trucks with both transponders, we recommend:
  • Use just the Oregon Green Light transponder.
  • Return the other transponder to Prepass.
  • Call 1-800-PrePass to ask them to enroll your Green Light transponder identification number into the PrePass preclearance system.
PrePass Transponders
Motor carriers with a PrePass transponder can sign up to use it in Oregon’s Green Light Preclearance Program. Carriers wanting to use their PrePass transponder in Oregon should contact the PrePass Customer Service Center at 1-800-PREPASS (1-800-773-7277). Their hours are Monday through Friday, 6 a.m. to 7 p.m. Mountain Time (excluding holidays). Request your PrePass transponder to be enrolled in the Oregon Green Light Program. PrePass will then contact us to complete the enrollment process.
 
Terms and Conditions of Transponder Usage in Oregon
  • Transponders are installed only on designated vehicles and in accordance with ODOT policies.
  • Carrier may bypass an open port or weigh station only when the transponder indicates a green light.
    Exception: Carriers whose vehicles are operating under a variance permit other than an extended weight permit must report to the weigh station even if they receive a green light.
  • The motor carrier is required to report any changes in the transponder application information to ODOT's Commerce and Compliance Division (CCD) at 503-378-6054.
  • The motor carrier is required to report any changes in the vehicles added to or removed from their fleet operations to the CCD at 503-378-6054.
  • The motor carrier agrees to allow their registration based state to provide information regarding their International Fuel Tax Agreement and their International Registration Plan to the Commerce and Compliance Division for the purpose of providing bypass preclearance to their commercial motor vehicles.
The Green Light Preclearance Program is also interoperable with the Drivewyze Preclear bypass service.

Motor carriers that enroll in the Drivewyze PreClear bypass service are eligible to bypass ten of Oregon’s preclearance locations with the remaining twelve sites soon to follow.

The new Drivewyze sites are located in:
  • Woodburn (north and southbound).
  • Booth Ranch (north and southbound).
  • Ashland (north and southbound).
  • Southwest of Juniper Butte (north and southbound).
  • Wyeth (westbound).
  • Rocky Point (westbound).
Drivewyze equipped carriers and owner operators do not need to enroll separately in the Oregon Green Light program and do not need to obtain a separate transponder.

Drivewyze PreClear is a software service that uses GPS and the internet instead of a transponder. It runs hands-free on many brands of Electronic Logging Devices (ELDs) and other in-cab telematics devices including tablets and smartphones.

For more information about Drivewyze, including a full list of compatible ELDs and other in-cab devices, please visit the Drivewyze website.
Carriers are advised to watch for the OPEN / CLOSED sign at the entrance to Green Light weigh stations. Regardless of a red light transponder signal, a weigh station CLOSED sign takes precedence and excuses trucks from stopping.
 
Although a Green Light weigh station may be manned and appear to be open, enforcement officers will occasionally activate the CLOSED sign when:
  • Trucks back up in the queue.
  • Officers are busy processing trucks.

Weight

  • The weigh-in-motion scales are set to err on the side of caution.
  • If your truck is under the legal limit or very close to that limit, the system may send a red light signal to your transponder and require that you check your weight on the weigh station static scales.

Safety

  • A truck will get a red light signal on its transponder if the trucking company has an unsatisfactory safety rating.
  • Green Light will also not preclear trucks operated by a company that is participating in the Performance and Registration Information Systems Management safety improvement program.

Registration and Tax

  • A truck will get a red light signal on its transponder if the trucking company´s account is suspended for failing to meet some regulatory requirement.
  • This can include failing to pay highway-use taxes or other fees.
Saved over 2.4 million hours by not having to enter Oregon weigh stations. Operating cost savings have exceeded $311 million.
​The program currently serves 6,284 companies with 58,099 trucks equipped with transponders. Company participation in the preclearance program has grown 46% since December 2017.
 
Vehicles given a “Green Light” by the preclearance program:
  • July 2020 — 29 million.
  • January 2018 — 25 million.
  • July 2015  —  20 million.
  • February 2012  —  15 million.
