Yes, you read it correct. IRDA allows three-year insurance for 2-wheelers. IRDA has made this possible by allowing general insurance companies to offer third party insurance for two-wheelers for a term of up to three years instead of one
year.

How much Premium you have to pay?
Isurers can charge three times the annual third party premium for two-wheelers as prescribed by them. So if you were paying Rs 900/- for one year then now you can pay Rs 2700/- for three years.

From where I can buy this policy?
Please wait, now insurers have to file products and once approved then you can buy these.
