-When it comes to auto insurance, you can [unk] without compromising your coverage. First, if you've moved closer to your job, participate in a carpool, or started working from home, you're putting fewer miles on your car. Auto insurance companies like that. You may be eligible for their most favorable rates, which could save you up to 25%. If your car is getting older, you may be paying for more coverage than you need. Look up the Kelley Blue Book value of your car. If your premium is more than 10 percent of that number, think about dropping comprehensive and collision coverage. Just make sure it's okay with your lender if you have a loan on the vehicle. You may also save by bundling auto insurance policies for all of the cars in your household, teens included, through the same carrier. The road to lower auto insurance rates is never long if you know where the shortcuts lie. In most cases, all it takes is a phone call.
