This depends on the state, or on local ordinances. Here in California, yes, motorcycles can use the carpool lanes.
A carpool lane allows people who have more than 2 people in the car to be able to use that lane to go through traffic easier.
A carpool lane is a special freeway lane only for buses and/or carpools. You may use a carpool lane or onramp if your vehicle carries the minimum number of people required for the carpool lane or you drive a low-emission vehicle displaying a special DMV-issued decal. Motorcycle riders may use designated carpool lanes, unless otherwise posted. Signs at the onramp or along the freeway tell you the minimum number of people required for the carpool and the hours the carpool requirement applies. The pavement in this lane is marked with a diamond symbol (◊) and the words "Carpool Lane." These lanes are also known as high-occupancy vehicle (HOV) lanes. Do not cross over double parallel solid lines to enter or exit any carpool lane except at designated entry or exit places. Vehicles towing trailers are typically not allowed to use carpool lanes because they must drive more slowly and are usually restricted to the right-hand lane.
Section 21460 Double Lines The purpose of the solid-white single line on the inside of the double yellow lines on buffered HOV lanes is to permit vehicles to legally drive to the left of the double yellow lines as defined in the provisions of this section.
To accomodate so-called high-occupancy-vehicles (2 or more passengers). The more people travelling in one car the fewer the cars on the congested roads.
The Diamond Lane is the carpool lane in California. The cars that are allowed in these lanes are White Clean Air and Green Clean Air vehicle sticker cars.
To use IPDE processes to protect motorcyclists while driving, they must be educated to this type of operation of a motor vehicle. IPDE stands for Identify, Predict, Decide, and Execute.
A dead body being transported as cargo does not count as an occupant. HOV lanes requires two or more occupants (presumably, living occupants) in the passenger compartment of the vehicle.
That is the correct spelling of the term carpool (ride sharing).
About half the amount of people in America carpool
all motorcyclists wear helmets, squids don't wear helmets.
It depends on the capacity of the car that number of people can carpool
Yes, definitely. This is very important, not only so that cars behind you know that you are switching lanes, but also the cars in the neighboring lane will know you are switching lanes.
