Barack Obama (Democrat) - I think he was a good president, albeit one who made some mistakes, but Obama was one of the most beloved and hated presidents in US history. His approval ratings were high when he left office, but those who hated him, REALLY hated him.
What is an HOV lane? High-Occupancy Vehicle (HOV) lane, also known as the carpool or diamond lane, is a traffic management strategy to promote and encourage ridesharing; thereby alleviating congestion and maximizing the people-carrying capacity of California highways.
HOV lanes are always marked with the HOV symbol. Many lanes also have large electronic message signs which display the required occupancy for using the lanes, the hours that HOV restrictions are in effect, and where to enter and exit. Some HOV lanes are barrier-separated, while others are simply in the left lane.
