1. Forgetting to Submit Forms
If you declined to purchase certain coverage, exclude drivers in the household, or if you are required to provide proof of prior insurance, you have a specified amount of time to submit the forms to your new insurance company or agent. If your form declining coverage or excluding a driver or proof of prior insurance is not postmarked by the date it is supposed to, your insurance rate will probably go up. This is because the price you were given was based on your decision that you don't want the coverage, the excluded driver will not be driving your vehicle (ever), or your declaration that you had at least 6 months of prior insurance. If you forget to send the requested information, that declined coverage may have to be added to your policy, or the insurance company may assume you did not have prior insurance since it did not receive proof that you did.
2. Buying a New Car
Getting a new car is exciting, but remember that you may pay more to insure it. Assuming nothing else changes, the cost of insurance generally goes down as your car ages. Though your new car may not require you to invest a lot of money in maintenance costs, you probably will invest more money in auto insurance for it - especially if you add coverage likes Comprehensive, Collision, Rental Reimbursement or towing.
3. Moving to a New Area
If you decide to move to a new city or even a new neighborhood, it could affect your insurance rate. This could go either way, as moving to a safer city might actually lower your rates. However, if you move from a smaller city to a larger city, or if you move to a densely populated city, your rates could be significantly higher due to a higher likelihood of accidents.
4. Incomplete Paperless Options
If you start your policy with an agreement that you will be what is considered "paperless" but you do not sign onto the website and confirm your decision and verify your email address, the discount will be removed from your policy. That means the rate goes up. No one can complete this process except you, so if you don't want to do it, don't agree to sign up for it.
