A system and method for triggering a vehicle inspection in a vehicle inspection bypass system. A handheld device transmits a signal containing the driver information in response to detecting an activation of an actuator on the handheld device. A vehicle mounted transponder detects the signal when the handheld device is in close proximity, and the driver information is stored in the transponder memory. Upon detecting an interrogation signal from a roadside reader, the transponder transmits a signal containing the driver information to the roadside reader. Based on the received driver information, a roadside controller determines whether a vehicle may bypass a vehicle inspection station.
An electronic toll collection transponder containing an orientation sensor for measuring the orientation of the transponder is described. The transponder measures its orientation and stores orientation data in memory.
