If you have been ordered by the court to take a defensive driving course, then you will likely not be able to get a discount on your auto insurance. But taking a course may allow you to keep your driver’s license, or remove points from your driving record depending on your state’s laws.
Even if you are unable to get an insurance discount right away, a defensive driving course may teach you techniques to make you a safer driver. If your insurer offers a telematics discount, you may be able to leverage your new, safe driving skills into that discount.
