摘要
A system involving transmitters adapted for mounting on trucks, buses, etc. and capable of energizing at least one transceiver along a highway which in turn sends a signal to a police control station to enable truck drivers to report a disabled vehicle and its general location; vandalism being avoided by mounting the transceivers on the top of light poles on expressways.
