These are on the high side, but there are still instances in which they won’t be enough to fully cover you. For example, if you accidentally hit a luxury car, replacing it could easily cost more than the $25,000 legal minimum for property damage coverage. If the other driver is injured, their medical bills could also exceed the $30,000 bodily injury minimum fairly easily. In each case, you’d be responsible for making up the difference yourself.
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.
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.
