If your car is old and not being financed, you’re likely okay to drop collision coverage and save some money on your auto insurance for military personnel. Be sure to speak with an agent to see how much you’d save. It’s important to know this because knowing how much your insurance would pay if your car was totaled will help you determine if the amount you’d pay insuring it with collision coverage would be more than what you’d get in the event your vehicle was a write-off.
