02B (DE Revision) Studies related to the Shared Lane Marking have primarily shown benefits in the reduction of "dooring" related crashes in urban areas where on-street parking is present and lateral positioning of bicycles is a concern. There have been no significant studies to date showing benefits from the placement of the Shared Lane Marking on rural or other types of roadways where parking does not exist and therefore driver comprehension of these markings on these roadways is a concern. Standard:
03 Shared Lane Markings shall not be used on shoulders or in designated bicycle lanes. Guidance:
