The company, Serenity Insurance, is one of the most popular SR22 insurance providers in America. Before choosing the company to get your SR22 with, it would be worth using a comparison website to make sure you are getting the best deal. Serenity Insurance prides itself on having low cost SR22 rates. This company also covers 47 states in America, making it one of the largest insurance companies in the market. On the ‘about’ page of their website, Serenity Insurance mentions that they work closely with alcohol treatment centres to get drivers suffering from alcohol related problems back on their feet. Which is much more than most insurance companies offer their customers.
