You will need to contact the court listed on your Texas citation for speeding 15 mph over the posted limit to find out if a TX defensive driving course is an option for you to take so that the speeding ticket can be dismissed.

To the best of our knowledge normally to take a defensive driving class to dismiss a ticket in TX you must have a Texas Driver's License.

While Michigan is not part of the Drivers License Compact (DLC) which requires member states to inform the licensing state of a driver of moving violation convictions, Texas is a member, your home state still does share information with other states and gets in information from other states. This means that likely the Texas courts will advise the MI SOS of your speeding ticket if you are convicted of it.

If traffic school or defensive driving class is not an option to you since you have an out of state ticket you may see if deferred adjudication is.

In Texas deferred adjudication is a type of probation that is only available after a plea of guilty or no contest. Once a defendant pleads guilty or no contest, the judge can postpone a finding of guilt and place the defendant on deferred adjudication. As long as the defendant follows the terms and conditions of the deferred adjudication, at the end of the probationary period, their ticket will be dismissed.

If the defendant violates the terms or conditions of the deferred adjudication, the probation can be revokes and if that happens, then the conviction does appear on the defendant's driving record or criminal record.

You would need to check with the Texas clerk of the court to find out if this speeding violation for 15 mph over the limit would still be shared with Michigan or not if you use deferred adjudication. If the ticket is shared with Michigan and it is put on your MI driving record then you insurance company would see it the next time they pulled your motor vehicle record (MVR).
