As the name suggests, a TPI policy is meant only for covering liability arising out of damage to life, limb and property of a third party involved in the accident. This policy does not cover the damage caused to the car of the owner and also does not provide any insurance cover for physical injuries or death of the car owner. Since the TPI policy provides cover for liability arising out of damage to life, limb and property of the third party involved in the accident—and since such liability can be unlimited—it does provide benefit to the car owner. But since it does not cover any damages to the car owner himself/herself, the utility of this policy is limited. Of course, the policy also helps comply with the mandatory legal requirement of car insurance.
The comprehensive car insurance policy, as the name suggests, provides insurance cover for damages caused to the car and the injuries caused or death of the owner on account of the accident as well as provides cover for the liability arising out of the damages caused to the property and injuries or death of the third party involved in the accident.
In view of the above, it can be said that the comprehensive car insurance policy makes much more sense than any other car insurance policy, notwithstanding the higher cost involved.
