Yes, and in fact it can be a very smart thing to do for many people. Many insurance companies will reward drivers who complete a traffic school course successfully with a discount of up to 15% on their car insurance rates. That can be over a $150 annual savings on average for taking a quick, fun, and simple course. If you would like to take an insurance discount traffic school course, first call your insurance company to find out if they will accept the course, then register. When you finish the course, send your completion certificate into your insurer.
