$750 every 6 months. I've had 4 speeding tickets in the past 5 years, but according to Texas law, you can take defensive driving once every 12 months to clear a pending ticket from your record, or you can take probation as often as you get off of it (if the judge will give it to you) for the pending ticket to not count on your record. Both of these cost slightly more than just paying the ticket and are a pain, but I have a clean record and don't worry about speeding.
