§ 11-308. One-way roadways and rotary traffic islands.

(a)    The State Roads Commission may designate any highway or
any separate roadway under its jurisdiction for one-way traffic and
shall erect appropriate signs giving notice thereof.

(b)    Upon a roadway designated and signposted for one-way
traffic a vehicle shall be driven only in the direction designated.

(c)    A vehicle passing around a rotary traffic island shall be
driven only to the right of the island.

§ 11-309. Driving on roadways laned for traffic.

Whenever any roadway has been divided into two 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 that lane until the
driver has first ascertained that the movement can be made with
safety.

(2)    Upon a roadway which is divided into three lanes and pro-
vides for two-way movement of traffic, a vehicle shall not be driven
in the center lane except (i) when overtaking and passing another
vehicle traveling in the same direction when the center lane is clear
of traffic within a safe distance, (ii) in preparation for making a left
turn, or (iii) where the center lane is at the time allocated exclusively
to traffic moving in the same direction that the vehicle is proceeding
and the allocation is designated by official traffic-control devices.

(3) Official traffic-control devices may be erected directing spec-
ified 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 direc-
tions of every such device.

(4) Official 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.

§ 11-310. Following too closely.

(a) The driver of a motor vehicle shall not follow another ve-
hicle more closely than is reasonable and prudent, having due re-
gard for the speed of the vehicles and traffic upon and the condition
of the highway.

(b)    The driver of any truck or motor vehicle drawing another
vehicle when traveling upon a roadway outside of a business or
residence district and which is following another truck or motor
vehicle drawing another vehicle, whenever conditions permit, shall
leave sufficient space so that an overtaking vehicle may enter and
occupy the space without danger, except that this shall not prevent
a truck or motor vehicle drawing another vehicle from overtaking
and passing any like vehicle or other vehicle.

(c)    Motor vehicles being driven upon any roadway outside of a
business or residence district in a caravan or motorcade whether or
not towing other vehicles shall be operated to allow sufficient space
