Purchase a transponder

Transponder benefits

Commercial vehicle drivers or carriers with a gross vehicle weight of 16,000 or more can purchase a transponder to be electronically screened as the commercial vehicle approaches a weigh station. The e-screening allows safe and legal carriers to bypass weight stations after checking the legal weight, safety rating and registration information.

Requirements

Transponders must be registered to a VIN with the commercial vehicle information used for electronic screening coming from the registration/cab card.

• The commercial vehicle registration/cab card must be current.
• An active USDOT number must be provided (Carrier Responsible for Safety).
• All required taxes and fees must be paid.

• To be notified when transponders are available, send a request to TransponderAdmin@wsdot.wa.gov.

Price

We charge a one-time $35 fee per transponder.

• When you receive the transponder, it belongs to you. You own the transponder.
• There are no additional fees for using a transponder in Washington.

Battery life

• Transponders have a 3 to 5-year average battery life (depending on use).
• Transponders do not have replaceable batteries.
• Once the transponder stops working, you will need to purchase a new transponder.
• Do not return non-working transponders purchased from us to WSDOT.
• Follow your regional guidelines for lithium ion batteries when disposing a transponder.
