HOV/HOT
Express Lanes
HOV stands for High Occupancy Vehicle. HOT stands for High Occupancy Toll. Both refer to barrier-separated, reversible lanes in the middle of Interstate 45, Interstate 69 / U.S. Highway 59 and Highway 290. The lanes flow toward downtown Houston in the morning and away from downtown in the afternoon. Lane usage, and whether or not a toll is required, depends on the freeway you’re using, time of day and total number of people in your vehicle.
