Abstract:
A security factor in an automobile plays an enormous role in saving lives during accidents. Accidents that happen during road trips are unfortunate and cause loss of precious lives. To minimize the loss of life several safety factors are being made mandatory, one among them is compulsory wearing seat belt. Driver normally avoids seat belt. The driver and co-driver are likely to get more injured during accident.

The seat belt keeps the occupants positioned correctly for maximum effectiveness for the airbag. In our project we have designed a security based seat belt usage in a proper way. Ours security system design allows the vehicle to start only if the seat belt is correctly locked. An LDR (Light Dependent Resistor) sensor is used for driver’s safety, to ensure that he locks the seat belt correctly. Thus the safety concern of driver and passengers is improved.

Conclusion:
The safety of the car is improved by our system. Now the neglect ion of safety factor like wearing a seat belt can be minimized. This design leads to the result that a number of accident can minimized.
