A system for monitoring and warning of dangerous driving conditions includes sensors mounted on the vehicle for detecting excessive moisture on the road surface, freezing temperature at the road surface, vibration of the vehicle in both horizontal and vertical directions, excessive vehicular speed, and drowsiness of the driver of the vehicle. The sensors are connected through detector circuits to an audible alarm and to a visual display which warns the driver of a dangerous driving condition.
