The availability of a discount for signing such an agreement varies among insurers and states. Your agent can give you guidance as to which insurers offer discounts. Moreover, you may not need collision and comprehensive coverage if you drive an older car. Ask your agent which discounts are available to you. The more people you allow to drive your vehicle on a regular basis, the greater the chances of your vehicle being in an accident.
Teenagers are especially expensive to insure because they are the least experienced drivers.
A driver's-ed course can help ease the burden of insurance costs since it teaches your teenager defensive driving techniques. If your child's high school does not offer driver's-ed, try to find one offered by another school or a private firm in the area. After all, the cost of driver's-ed could be cheaper than the extra cost of your insurance. An adult's driving experience can also affect your rates significantly. Don't assume that every adult you know has been driving since age 16 or is a competent driver with a clean record.
