270 in MD at 1:56 pm. In the  metro DC area, carpool lanes are commonly referred to as HOV (High  Occupancy Vehicle) lanes. In addition, HOV restrictions would not  have been in effect at that time of day. If Lynch was headed  southbound, HOV restrictions are only in place from 6:30 am to 9:30  am. If he was headed northbound, the restrictions are applicable  from 3:30 pm to 6:30 pm. Also, the highway cameras that captured  Lynchs infraction belong to the county, not the MD State Police,  and are typically used to monitor traffic flow (not catch HOV lane  violators).
