PrePass is the most reliable, widely utilized weigh station bypass system in North America. There are PrePass-equipped sites across every corridor north to south, east to west and hundreds of places in between.
With PrePass, pre-cleared vehicles can continue at highway speeds without having to stop. PrePass not only saves fleets time, fuel and money, but it helps create greater efficiencies for shippers and supports improved safety for all highway users.
Through PrePass, over a half million commercial vehicles from qualified fleets are electronically pre-screened for compliance with federal and state safety and credential requirements. Within seconds of approaching a PrePass-equipped inspection facility, PrePass’ electronic pre-screening quickly lets drivers know if they’re cleared to stay on the road and bypass the truck scales at highway speed, or if they need to pull in.
Technology That Works. Every Time.
The small plastic transponder box on PrePass equipped trucks might look simple at first glance, but the technology inside is the best in the industry.
That’s because PrePass operates with an Advance Vehicle Identification (AVI) reader and vehicle in-cab transponder platform. No other data transmission model can replicate the data accuracy and transmission speed of the transponder system. For weigh stations not equipped with transponder readers with strong cellular connectivity, PrePass includes the MOTION mobile application. This combination of transponder and bypass app means you leverage the most opportunities to bypass weigh stations.
My company depends on the time and fuel savings PrePass provides, and my drivers view pre-clearance as a real benefit that makes them more efficient. Therefore, PrePass is a great recruiting tool. In fact, many drivers ask us if we offer PrePass early in the interview process.

MOTION™ Bypass App
PrePass customers can expand their ability to bypass weigh stations with the MOTION bypass application. Available on Apple iOS, Android and select telematics devices, the MOTION app uses cellular signals to enable bypassing where RFID transponder readers are not installed. The PrePass transponder and bypass app together provide the reliability benefits of RFID with the coverage benefits of cellular technology. The MOTION app is an added benefit of PrePass service.

Third Party Bypass Integration
One of the benefits of the PrePass transponder is co-operability with other transponder-based bypass programs. By registering the PrePass transponder in these other programs, carriers can bypass at NORPASS, Oregon Green Light and Weigh2GoBC locations using one transponder.
How PrePass Works
PrePass states have placed signs on the highway alerting vehicles that they are approaching a PrePass-equipped weigh station. As with all weigh stations, trucks are required to be in the right hand lanes. At some locations, there will be two lanes available for bypass, but trucks must remain prepared to stop in the event that they don’t get a green light.
Transponder: Roadway signs alert the driver when approaching the PrePass site. Drivers merge into the right lane. An RFID communication between the in-cab transponder and the reader identifies the truck.
PrePass MOTION app: The MOTION app alerts the driver that a weigh station is approaching and to merge into the right lane. A cellular connection is established between the in-cab device and the weigh station.
The PrePass system electronically checks the carrier’s safety and vehicle’s credential (e.g. vehicle registration, IFTA) status. In some states the system also checks the truck’s weight to ensure that it is compliant with the jurisdiction’s regulations. Based on a truck’s clearance status, the PrePass system will send a signal to the transponder and/or the PrePass MOTION app.
Transponder: The driver receives a screening result visually and audibly. A green light indicates a bypass and a red light indicates that the driver must pull into the weigh station.
PrePass MOTION app: A “Pull-In” or “Bypass” decision displays to the driver. If also using a transponder, a “Follow In-Cab Transponder” alert displays on the PrePass MOTION application.
4. Random Selection
To help maintain system integrity, some PrePass trucks are randomly selected and receive a red light or Pull In alert, requiring them to pull into the weigh station where a carrier’s compliance can be confirmed.
5. Last Recall
Transponder: The bypass screening signal will continue to flash for 15 minutes after passing the weigh station. This provides confirmation of the vehicle’s bypass status for both the driver and enforcement.
PrePass MOTION app: Last Decision Recall is available within the app’s Main Menu. This allows drivers to show an officer the most recent site passed, the decision alert screen and date of last decision.
