§ 54-236. Driving on divided or controlled-access highways.

(a)

Whenever any highway has been divided into separate roadways by leaving an intervening space or by a physical barrier or clearly indicated dividing section so constructed as to impede vehicular traffic, every vehicle shall be driven only upon the right-hand roadway, unless directed or permitted to use another roadway by official traffic-control devices. No vehicle shall be driven over, across or within any such dividing space, barrier or section, except through an opening in such physical barrier or dividing section or space or at a crossover or intersection as established, unless specifically prohibited by official signs and markings.

(b)

It shall be unlawful for any person to drive a vehicle onto or from any controlled-access roadway except at such entrances and exits as are established by public authority.

(c)

Whenever an acceleration lane has been provided in conjunction with a ramp entering a controlled-access highway, and the ramp intersection is not designated or signed as a stop or yield intersection as provided in sections 54-258 and 54-259, drivers may use the acceleration lane to attain a safe speed for merging with through traffic when conditions permit such acceleration with safety; provided, that traffic so merging shall be subject to the rule governing the changing of lanes as set forth in section 54-234.

(d)

Wherever a deceleration lane has been provided in conjunction with a ramp leaving a controlled-access highway, drivers shall use such lane to slow to a safe speed for making an exit turn after leaving the mainstream of faster-moving traffic.
