Wisconsin automobile insurance was made mandatory on June 1, 2010 and if a person decides not to carry insurance on their vehicle, they may cover their vehicle with other assurances that include personal funds, a security bond, or become self-insured. For those who purchase liability, they must have at least $50,000 for the injury or death of a single person, $100,000 for the injury or death of multiple people, and $15,000 in property damage. 
Wisconsin state law also requires that motorists carry uninsured and underinsured motorist coverage with bodily injury amounts of no less than $100,000 and $300,000.  This is to protect you in case you are involved in an accident with an uninsured or underinsured motorist.
There are other instances in which Wisconsin automobile insurance may be required. One very common instance is when you finance a car. It is not that the state requires you to have coverage, but it is the lender's choice. The lender is the one concerned with the car being protected because it belongs to them until the car is paid off. Full coverage is also required because the actual car is protected in addition to bodily injury coverage that protects you. The insurance company, however, wants to ensure that damages can be recovered on the car, mainly in hopes that the car will be repaired.
Uninsured motorist coverage is useful in that it provides you with the protection that you need in case you are in an accident with an uninsured or underinsured motorist.
Although it is Wisconsin state law that an individual's automobile is insured, there are those individuals who are still driving without it. If caught by a law enforcement officer, there would be consequences. When they are involved in an accident that is their fault, there are consequences as well. You can hold them liable for the damages and they may need to satisfy bodily injuries that they inflict upon you by selling their own assets. However, not every uninsured or underinsured motorist has the assets to sell to satisfy the liability.
It is important to note that liability does not cover damage to your automobile, which is why the state requirement is for bodily injury coverage alone. At least if you are injured in an automobile accident and the fault lies on a person with little or no insurance, you have protection to pay for your medical expenses.
If you find that you want to protect your vehicle, you may want collision coverage as a part of your Wisconsin automobile insurance. Collision pays for the damage that is done to your vehicle by someone else. You can take advantage of the collision coverage on your Wisconsin insurance policy even if the accident was your fault.
