West Virginia and Maryland are both members of the Drivers License Compact (DLC). The DLC allows for traffic violations you receive in other states to be reported back to the state in which you are licensed. Your home states laws then dictate whether the out of state moving violation conviction is placed on your driving record and assessed points.
The West Virginia Division of Motor Vehicles (DMV) has decided to place moving violation convictions, regardless of what state they are committed in, on a motorist WV driving record. The WVDOT Division of Motor Vehicles states that points are assessed for all traffic violations committed anywhere in the US. Drivers convicted of multiple offenses arising out of the same incident will be assessed only the points appropriate to the most serious offense.
So traffic violations you receive in other states (like Maryland) will become part of your WV driving record and points will be assessed. In West Virginia it is 5 points for a speeding ticket for going 15 or more mph over the limit, 3 points for speeding 10 to 14 mph over the posted limit and 2 points for 5 to 9 mph over the speed limit.
Points in West Virginia are assigned according to the severity of the offense. Points for a given infraction remain on a driver's record for two years after the date of the conviction. The infraction itself remains on the driver's record for seven years.
The WV DMV notes that they can deduct three points from the licenses of drivers who complete an approved Defensive Driving Course. The DMV cannot deduct points on a record if the licensee completes the course prior to accumulating points on their record.
