reserved lanes
They are called diamond lanes because they are marked with big white diamond shapes on the pavement. These lanes are for a special kind of traffic, typically cyclists.
Vehicles with two or more occupants
A carpool lane is typically marked with a diamond symbol, which indicates that the lane is reserved for vehicles with multiple occupants, such as carpools or buses. This diamond symbol is often accompanied by signage that specifies the minimum number of passengers required to use the lane. The purpose of these lanes is to promote carpooling and reduce traffic congestion.
In driving, a diamond symbol indicates special lanes or areas designated for specific types of vehicles or uses, such as high-occupancy vehicle (HOV) lanes or bus lanes. These lanes are typically reserved for vehicles with a certain number of occupants or for public transportation. The diamond symbol helps drivers quickly identify these lanes and understand their intended use, ensuring smoother traffic flow and promoting carpooling or efficient public transit.
HOV lanes are indicated by diamonds on pavement and on road signs; sometimes the lanes are called "diamond lanes."

In most instances a lane of travel will be marked as the lane that is merging with the other lane or lanes. If so, the lane that is NOT ending has the right of way.

A HOV sign stands for High Occupancy Vehicle and designates lanes reserved for vehicles with a certain number of occupants, usually two or more. These lanes are intended to promote carpooling and reduce traffic congestion.
Vehicle traffic lanes
On urban surface roadways - with two adjacent travel lanes you may pass on the right if the vehicle traffic in the left lane is moving slaower than you are. Which is NOT TO SAY that it is permissible to cut in-and-out of traffic to further your progress.
