Delaware Code Title 21. Motor Vehicles § 4196. Bicycling on right side of roadway; exceptions

(1) When overtaking and passing another bicycle or vehicle proceeding in the same direction;

(2) When preparing for a left turn at an intersection or into a private road or driveway;

(3) When approaching an intersection where right turns are permitted and there is a dedicated right-turn lane, in which case a person may operate a bicycle in this dedicated lane, even if the bicycle operator does not intend to turn right;

(4) When reasonably necessary to avoid conditions including, but not limited to fixed or moving objects, parked or moving vehicles, bicycles, pedestrians, animals or surface hazards;

(5) When a paved roadway shoulder exists, in which case a person may operate a bicycle in the roadway shoulder with due regard for any traffic control devices intended to regulate or guide traffic or pedestrians;

(6) When a part of a roadway has been set aside for the exclusive use of bicycles including contra-flow bicycle lanes, left-handed cycle tracks or bicycle lanes on 1-way streets and 2-way cycle tracks or bicycle lanes, in which case a person may operate a bicycle in the designated bicycle lane or cycle track; or

(7) When operating a bicycle upon a 1-way highway with 2 or more marked traffic lanes and a posted speed limit of less than 30 miles per hour, in which case a person may operate a bicycle as near the left-hand edge of such roadway as judged safe by the bicycle operator.

(1) Operating bicycles side-by-side does not constitute an impediment to normal traffic at times of no conflicting traffic, if motor vehicle traffic can overtake in the adjacent lane, or if the lane is too narrow for a bicycle and a vehicle to travel safely side-by-side within the lane.

(2) On a laned roadway, persons operating bicycles side-by-side shall do so within a single lane.
