"The overall percentage increase in the motor third party portfolio works out to 18.9 per cent. The above rates will be effective from April 1, 2013," Irda said in a notification on Monday.
Charges for the third party insurance cover as per the notification will go up for two-wheelers, passenger cars and commercial vehicles.
For passenger cars not exceeding engine capacity of 1,000 cc, the revised third party premium is proposed to be hiked by 20 per cent to Rs 941 per annum. For two-wheelers exceeding 350 cc, the premium would go up by 18.30 per cent to Rs 804.
For goods carrying vehicles, excluding three-wheelers, with carriage capacity exceeding 40,000 kg, the premium would be Rs 15,035 per annum.
There is no increase in case of three-wheelers used for carrying passengers for hire or reward with carrying capacity not exceeding 6 passengers.
In case of four-wheelers used for carrying passengers with carrying capacity exceeding 6 passengers for hire, the increase is to the extent of 20 per cent from the existing level.
The earlier hike which was done in March 2012 was disputed by transporters' association which had fought a legal battle with Irda and general insurers in the Calcutta High Court. However, after eight months of litigation, the court had passed verdict in favour of the hike.
Earlier in 2012, while asking domestic general insurers to hike the provisioning - capital to be set aside to pay the future claims as it takes years to settle claims under this category - against the third party motor portfolio, Irda had assured general insurers that it will allow them to hike the third party motor rates gradually.
Irda had dismantled the third party motor insurance pool from April 1, 2011 thereby linking premium rate with the prevailing market rate.
