Yes, it is possible that your home licensing state will assess you points for a traffic offense that you were ticketed and convicted of out of state.
Most states have reciprocal agreements with each other or otherwise have decided to share moving violation convictions that were received out of state back to the licensing state of the driver who received the citation. This can be for a minor offense such as a speeding ticket or a major offense such as a DUI.
The main reciprocal agreements with regards to traffic violations are the Drivers License Compact (DLC) and Non-Resident Violator Compact (NRVC). There are states that do not take part in any of these compacts but instead have their own separate agreements that their Motor Vehicle Administration has made with other states.
As a member of the DLC member states are required to report ticket convictions received by a motorist back to the state where they are licensed to drive. Their own state then determines if this offense will be placed on their driving record and if any points will be assessed.
The members of the DLC: include Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, District of Columbia, Florida, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, South Carolina, Texas, Utah, Vermont, Virginia, Washington, West Virginia and Wyoming.
Thus this leaves the states of Georgia, Massachusetts, Michigan, Tennessee and Wisconsin as non-members though most of these states still have their own agreements with other states to exchange information regarding traffic tickets.
So most all states notify your home state when you are convicted of a moving traffic violation. Your home state then determines, based on state laws, whether the offense will be placed on your driving record and if points are assessed. For example New York and Pennsylvania get notified about their licensed motorists out of state violations however for the most part do not place the violation (unless serious like a DUI) on your driving record and also no not assess points.
Some states, like Ohio, place out of state violations on your driving record but do not assign it points.
Other states such as New Jersey and California put the violation on your record and then have their own violation points list just for out of state convictions. In NJ it is 2 points for out of state offenses that are placed on your motor vehicle record (MVR).
In several states the DMV will place the out of state traffic offense on your driving record and assign it points as if the violation occurred in state. Florida is one such state and so is Texas. The Texas Department of Public Safety (DPS) states that any out of state conviction for a traffic offense that meets the definition of a moving violation in TX will accrue points.
Some people believe the way to keep an out of state offense off their driving record and from being assigned points is to ignore it. That turns out to be a bad choice normally since the states do share so much information now and so if you fail to comply with the ticket your home state is informed and typically will suspend your license until you take care of the out of state citation.
The Non-Resident Violator Compact (NRVC) requires member states to suspend the driver's license of those who get traffic tickets for moving violations in other states and fail to pay them or otherwise legally take care of them.
Members of the NRVC include: Alabama, Arizona, Arkansas, Colorado, Connecticut, Delaware, District of Columbia, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia and Wyoming.
This leaves the states of Alaska, California, Michigan, Montana, Oregon and Wisconsin that are not members of the NRVC. Again they may have their own agreements though with other states and may still suspend or penalize a driver that does not pay their out of state ticket.
