A speeding ticket in Indiana for going 16 to 25 miles per hour over the posted speed limit is a 4 point offense if you have an IN driver's license. It would appear that you were driving through Indiana though, so you will need to find out from the state in which you are licensed if they assess points for out of state traffic violations.

Forty plus states are part of the Drivers License Compact (DLC) including Indiana. This compact requires member states to report tickets received by motorists back to the state in which their license is from. Per the DLC, Indiana has decided that they will inform non-resident's drivers home state of traffic tickets received in IN.

Some states do not assign points for out of state citations; some assign a certain number of points for any out of state ticket while others assess points as if the ticket was received in your home state. Check with your state's Department of Motor Vehicles to find out how your state deals with a traffic citation received in a different state.
