The key difference in collision vs. comprehensive coverage is that, to a certain extent, the element of the car driver's control. As we have stated before, collision insurance will typically cover events within a motorist's control, or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," that are typically out of your control when driving. These can include such events as a spooked deer, a heavy hailstorm, or a carjacking.
Next, take a good hard look at your driving record and credit report, and clean both up if they’re not in good shape. Moving violations, citations for driving under the influence, accidents, and a low credit score all tell car insurance companies you’re at higher risk of being in an accident, making a claim, and costing them money. Some car insurance companies will give you a discount if you can prove you’re a safe driver by installing a tracking device in your car, which can lead to lower rates over time (however, if the tracker shows you routinely drive in an unsafe manner, your rates might go up). A few years without a citation or an accident, as well as a steadily improving credit score, can help you save on car insurance.
Financial experts often say it’s smart to drop collision when you drive an old car, then put your car insurance savings in a fund earmarked for emergency repairs or buying a new car. However, when you’re trying to decide when to drop collision coverage, the answer really comes down to your personal finances. “If you’re not absolutely sure that you could deal with paying for repairs or completely replacing your vehicle at a moment’s notice, or else going without a vehicle until you could save for a replacement, it’s best to err on the side of caution and pay the extra premium for collision coverage,” The Simple Dollar advises.
