Yes! Many auto insurers in Texas offer a discount of up to 10% when you provide proof of completing a state-approved driver safety course.
Most providers will reduce your monthly premiums by 2–10% if you meet their requirements. Just keep in mind — if the court ordered you to take the course (or you took it specifically to dismiss a ticket), some insurers may not offer the discount. It's best to check with your insurance company directly for their specific policy.
