As street planners often lay out painted bike lanes in the door zone, many bicycle safety advocates advise cyclists to maintain a safe distance from car doors nonetheless and disregard such markings to do so. However riding on the margin of the bike lane places a cyclist in increased proximity to overtaking vehicles and also at risk of being squeezed closer into the doorzone. Other advocates therefore instruct bicyclists to take control of the full travel lane to avoid dooring, considering it the safest position overall.
