How many meters is between the normal road and this HOV road?
Not normally. Normally it is simply a minimum restriction on the number of occupants of the vehicle. The theory being that there will be less pollution and less congestion with this incentive to carpool. Separation between a HOV lane and the normal road varies from the width of a painted stripe to tens of meters.
