Many cyclists believe they are safer and more comfortable riding as far to the right as possible. They fear being passed uncomfortably close by a motorist or they feel intimidated by impatient drivers. Riding too far to the right is very dangerous for several reasons: it puts the cyclist in the danger zone of poor sightlines and opening car doors; it invites motorists to attempt to pass too closely; and it takes away the cyclist's escape route to the right in the event of the unexpected. Take responsibility for your own safety and decide when to take the lane, even if other traffic must occasionally slowly follow you until there’s an opportunity to pass by crossing over to the next lane.
