In a country like India, where 20 million people are hospitalized every year due to road accidents, it is quite evident that there is something off with roads and drivers. Roads in the urban areas are highly congested. Moreover, accidents and deaths can also be caused by the intake of alcohol/drugs consumed by drivers, overloaded vehicles, defects in motor vehicles, bad infrastructure, faults of pedestrians. So, in this paper a multipoint collision detection and prevention system using Light Fidelty (Li-Fi) for smart cars is proposed that can be an effective way in preventing, but not completely eradicating, the number of accidents to a decent extent. Li-Fi uses LED to transmit burst of data to one or more receiver. The system uses Arduino Uno to make the system behave according to the algorithm used. Depending on the distance between the vehicles, the vehicles behind slow down or stop completely. In case of a collision alert message, the receiver also raises an alarm for the driver.
