@ GrandRk Detarriff is not available in india as if now. its basically a standard minimum requiremnet policy in addition to that a customer can add other covers.
its like a comprehensive insurance covers own vehicle damage, driver hospitalisation, third party damage, third party hospitalization,
so lets say third party insurance is bare minimum in today's day upon that a customer can add what he wishes to be covered after that. so there would be decrease in premium you pay, but this option isn't available in India AFAIK
for motor insurance. might be for small scale industries and large scale industries this exists. experts please shed some light on this.
