Krishna suggests using a smart card that contains electronically all the documentation required to drive a vehicle and to start a vehicle this card has to be inserted into electronic identifier, and it also makes easy to trace missing cars.  

This idea struck him during discussions at school on traffic regulations.

He feels, "Many people forget the license at home. So there should be some system to make it mandatory that without license, the vehicle will not start."

Lakshya Kaura loved to listen music on his head phones and also wanted to take heed to road safety. He shared his thought with his friends and all six of them put their heads together to come up with an innovative solution: headphones fitted with sensors to pick up external sounds.

So, if a vehicle honks within 10 metres, the headphones automatically stop playing and sound an alert.

There are two ideas by Rajashree , one which prevents use of cell phone while driving and other one alerts about the visitor.

A device with a place for inserting a mobile is fixed on the car dashboard or handle of a two-wheeler. The vehicle moves forward only if the mobile is inserted into this device. 

Her next idea is to have personalized doorbell ringtones so you know who is at the door beforehand. The doorbell has unique codes assigned to different individuals. So when a guest presses their code, the doorbell rings with a specific sound.
