A vehicle status device and system for remotely updating and monitoring the status of a vehicle. The vehicle status device is located in a vehicle and reports status information for the vehicle and an owner to an interrogating unit. The device includes a database of status information for the vehicle and owner. An update receiver in the device receives updated information from a wide area paging network for storage in the database. An interrogation receiver receives an interrogation signal from the interrogating unit, and a response transmitter transmits encoded status information, including a vehicle identification (VID), to the interrogating unit in response. The updating and monitoring system also includes an interrogating unit which includes an interrogation transmitter for transmitting the interrogation signal to the vehicle status device, and a response receiver for receiving the encoded status information from the vehicle status device. A processor decodes the encoded status information and translates it into plain language for presentation to an operator. The system may be implemented as a ticket-less toll system by providing a database of subscribers in which VIDs are matched to subscriber identities, credit card information, and current status as valid subscribers.

1. A vehicle status device mounted in a vehicle for reporting status information for the vehicle to an external interrogating unit, said status device comprising:a control processor; a device memory interfaced with the processor that stores status information for the vehicle; an update receiver that receives updated vehicle status information from an external central database and passes the information to the processor for storage in the device memory; a radar receiver that receives a dataless radar signal from an external policeradar transmitter, and passes an indication of receiving the radar signal to the processor for retrieval of the status information from the device memory; and a response transmitter that transmits the retrieved vehicle status information to the external interrogating unit in response to the radar receiver receiving the dataless radar signal.
