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.
NerdWallet averaged rates for 40-year-old men and women for 20 ZIP codes in each state and Washington, D.C., from the largest insurers, up to 12 in each state. “Good drivers” had no moving violations on record and credit in the “good” tier as reported to each insurer. For the other two driver profiles, we changed the credit tier to “poor” or added one at-fault accident, keeping everything else the same. Sample drivers had the following coverage limits:
Third Party Car Insurance is a risk cover, under which the insurer compensates any legal liabilities claimed by the other party, in case the insured vehicle is at fault. However, as per the Motor Vehicles Act 1988, Section 146, plying an uninsured vehicle on Indian roads is an offence. This is why liability insurance is also known as ‘Act Only’ plan. This plan doesn’t cover the insured or his car.

Our data shows that 7% of Progressive drivers with comprehensive coverage have a comprehensive claim in a given year, and the average repair is about $1,400. Without comprehensive, that's how much you may have to pay out of pocket. Keep in mind, repair costs can vary widely based on your damage and how much your car is worth. Typically more expensive cars cost more to repair.
Comprehensive insurance is commonly confused with collision. They both insure your car but cover different events. Collision covers car accidents, and comprehensive covers events out of your control. Think of it like this: Collision is colliding with something else (other than animals). Comprehensive is basically all other events. Accidents with animals are covered by comprehensive (and not collision) because these accidents are considered out of your control.
