What does "HOV 2+" mean on the carpool lane sign

HOV stands for high-occupancy vehicle. HOV lanes are also commonly referred to as carpool lanes. The 2+ refers to the number of people in the car. In this case, if the driver has at least one passenger, he is able to use the carpool lane. Many metropolitan areas are encouraging carpooling as it reduces traffic congestion and shortens commute times.
