Del. P.J.I. Civ. § 6.6.3

Title 21 Del. C. § 4122 provides as follows:

Whenever any roadway has been divided into 2 or more clearly marked lanes

for traffic, the following rules in addition to all others consistent herewith shall

apply:

(1) A vehicle shall be driven as nearly as practicable entirely within a single

lane and shall not be moved from such lane until the driver has first ascertained that

such movement can be made with safety.

(2) Upon a roadway which is divided into 3 lanes for 2-way traffic, a

vehicle shall not be driven in the center lane except when overtaking and passing

another vehicle where the roadway is clearly visible and such center lane is clear of

oncoming traffic within a safe distance, or in preparation for a left turn or where such

center lane is at the time allocated exclusively by traffic-control devices to traffic

moving in the direction the vehicle is proceeding.

(3) Traffic-control devices may be erected directing specified traffic to use

a designated lane or designating those lanes to be used by traffic moving in a

particular direction regardless of the center of the roadway, and drivers of vehicles

shall obey the directions of every such traffic-control device.

(4) Traffic-control devices may be installed prohibiting the changing of

lanes on sections of roadway and drivers of vehicles shall obey the directions of

every such device.
