Besides the legal clause, Third Party Insurance comes in handy when your vehicle hits another vehicle. You can’t measure the level of damage as a result of an accident - it might lead to death as well. In such instances, the victim is allowed to register a case claiming for compensation. Here your third party motor insurance comes into the picture. It covers the insured vehicles in case any liability claim arises out of bodily injury, property damage, or death of a person. As per the guidelines of IRDA third-party property damage cover is limited up to 7 lakhs. Moreover, sticking to third party liability insurance is a wise idea if you own an old car and don’t want to spend your hard-earned money on it.
Let's use the aftermath of Superstorm Sandy as an example to illustrate the differences between collision and comprehensive. Within that storm, let's consider two events that might have happened: 1) a heavy tree branch fell on your car, or 2) you swerved to avoid a falling tree branch and wound up crashing into a tree. In the first event, you had no control over when or why a tree branch would fall on your car. This kind of accident would get reimbursed under your comprehensive policy. In the second situation, you were driving the car and ultimately swerved into the tree, which makes it a collision, and collision insurance therefore pays for the damages. Events like the hypothetical ones stated above are why it's important to differentiate between the two types of coverage.
Definition: Motor third-party insurance or third-party liability cover, which is sometimes also referred to as the 'act only' cover, is a statutory requirement under the Motor Vehicles Act. It is referred to as a 'third-party' cover since the beneficiary of the policy is someone other than the two parties involved in the contract (the car owner and the insurance company). The policy does not provide any benefit to the insured. However, it covers the insured's legal liability for death/disability of third-party loss or damage to the third-party property.
Comprehensive insurance is a coverage that helps pay to replace or repair your vehicle if it's stolen or damaged in an incident that's not a collision. Comprehensive typically covers damage from fire, vandalism or falling objects (like a tree or hail). If you're financing or leasing your car, your lender likely requires comprehensive coverage. If you own your vehicle outright, it's an optional coverage on your car insurance policy.
