ABSTRACT:
An alarm system is used in conjunction with a land motor vehicle to warn a driver that he is either too close to a roadway edge or is approaching that edge too rapidly. The alarm system uses material in a line marking the edge of the roadway that generates nuclear particles, and includes a detector system that activates a visual alarm if the vehicle is merely drifting towards the roadway edge and activates an audible alarm if the vehicle approaches the edge so rapidly or is so close to the edge as to require a sharp swerving action by the driver.
