One of the most serious driving offenses is a DWI. Once you have been convicted of drinking while intoxicated, insurance companies automatically view you as a high risk, and if you have two of them within a 10 year period the risks are even higher. It isn't that you are necessarily more dangerous, but the risk of you driving under the influence and getting into a serious accident is much higher, and that increases your costs.
Traditional car insurance companies may not want to underwrite a policy for someone with more than one DWI, but high risks insurers is still a viable choice. Because you are a high risk driver, you will have to pay higher rates than someone without any DWI's, but car insurance is available to anyone who can legally drive a car.
