Bicyclists should not be allowed to ride on major roadways where there is no dedicated bike lane or where there is not enough space to allow a bicyclist to ride without causing regular vehicular traffic to swerve around the bicyclist. In these cases, bicyclists should use the sidewalk. However, in cases where there is no sidewalk or any alternative, bicyclists may be allowed to ride in the street. Also, bicyclists should not be allowed to use automotive turning lanes, but rather should use crosswalks, unless crosswalks are not available.
