A system that directly monitors a physical condition of a driver. The system includes a portable device carried by the driver. The portable device includes a perspiration sensor, for detecting biological information serving as an index representing the physical condition of the driver, and a transmitter circuit, for generating a transmission signal including the biological information detected by the perspiration sensor. The monitoring device, which is installed in the vehicle, includes a receiver circuit for receiving the transmission signal from the portable device. A microcomputer and a display inform the driver of his or her physical condition based on the transmission signal received by the receiver circuit.
