Half a century ago the standard speeding fine in Texas was $10 / mph over the limit up to but not including 10, then $20 per mph over the limit if you were 10 or more over the limit up to 20, after that they got really serious. For that reason 9 mph speeding fines are common. It is the arresting officer's way of giving the speeder a break. Note too the fine also includes court costs and for a jury trial $200 is not unusual. Even the fine is uncontested court costs can run $50 to $100.
I neglected to mention that if you have a clean record for the last three years and you not over 10 mph over the limit you can elect to take a safe driving course and if your record remains clean for three years after that the record is expunged. You will still pay for the safe driving course and court costs.
