In California, most are 24/7. When they're not, they're either closed to all traffic and treated as dead space, or PSV-only outside HOV hours. All traffic is prohibited from making lane changes in areas where the white-orange-orange lines are present, with the general access lanes functionally being the right shoulder for HOV traffic, and the HOV area treated as the left shoulder for general access traffic. Every 1-3 miles where lane changes are permitted, lane changes in and out of the HOV area is permitted for traffic allowed in that lane, no other locations. These restrictions are strictly enforced, as the difference in speed between the HOV lane and general access is frequently in excess of 60 MPH during peak traffic periods in sections where the HOV lane is isolated. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
