Crash alarm

摘要

The device installed on vehicles will be activated (according to the entering or the leaving of the highway toll) by the external stationary device fitted near the entry and exit toll points. Upon entering the highway with the activated device, an alarm signal will be emitted if another vehicle involved in an accident (within a range of two kilometres) switches on its "Crash Alarm" through the air bag sensor. This alarm signal will be recognized by the driver through a sound signal inside the passenger compartment and by a light signal outside the car (double indicators lights alternatively to stop lights). <IMAGE>
