As of May 2018, all new vehicles are required to have rearview video systems (backup cameras) in accordance with NHTSA regulations. Although this type of vehicle technology has proven to reduce the number of accidents caused by human error, it has also made common and previously inexpensive repairs—such as bumper replacement—more expensive, increasing the potential losses for insurance companies.
Insurance companies cannot raise premiums instantaneously to reflect incurred losses. That's because rate changes—in most states—must be submitted and reviewed by the state's department of insurance before they can go into effect. As a result, rate changes that are brought on by a loss-causing event—such as a hurricane—may take some time to go into effect.
The cheapest car insurance, period, will likely carry the minimum coverage required in your state. In most states, this is liability insurance only, which covers property damage and medical bills for others due to accidents you cause. Some states also require uninsured and underinsured motorist coverage, which pay for your injuries or damage if an at-fault driver doesn’t have enough insurance.
