Both collision and other than collision (comprehensive) coverages are in Part D. Collision is defined as losses you incur when your auto collides with another car or object. For example, if you hit a car in a parking lot, damages to your car will be paid under your collision coverage. Comprehensive covers most other direct physical damage losses including fire, vandalism, flood, theft, glass breakage, and much more. (It’s very comprehensive!). It’s important to know the differences between collision and comprehensive coverage to make an informed buying decision. Also keep in mind that your deductibles in these two categories are often different. You also have the option of purchasing a “full glass coverage” option which eliminates your deductible for all glass claims to your vehicle.
