Mohtaram Bhai Sahib,
Remember the 3 Es of prevention:
1. Engineering: Every car should be installed with safety belts.
2. Education: Educate the car users that safety belts are your friends.
3. Enforcement/enactment: Fines for those not using seat belts.
Here is an example from wikipedia: Injury prevention - Wikipedia, the free encyclopedia
Engineering: vehicle crash worthiness, seat belts, airbags, locking seat belts for child seats.
Education: promote seat belt use, discourage impaired driving, promote child safety seats.
Enforcement and enactment: passage and enforcement of primary seat belt laws, speed limits, impaired driving enforcement.
Regards.
