On those sections of highways which are or become a part of the National System of Interstate and Defense Highways and other controlled-access highways, it shall be unlawful for any person:

(1) To drive a vehicle over, upon, or across any curb, central dividing section or other separation or dividing line on said highways.

(2) To make a left turn or a semicircular or U-turn except through an opening provided for that purpose in the dividing curb, separation section, or line on said highways.

(3) To drive any vehicle except in the proper lane provided for that purpose and in the proper direction and to the right of the central dividing curb, separation section, or line on said highways.

(4) To drive a vehicle onto or from any controlled-access highway except at such entrances and exits as are established by public authority.

(5) To stop, park, or leave standing any vehicle, whether attended or unattended, on any part or portion of the right-of-way of said highways, except in the case of an emergency or as directed by a peace officer, or at designated parking areas.

(6) To fail to yield the right-of-way when entering the highway to any vehicle already travelling on the highway.

(7) Notwithstanding any other subdivision of this section, a law enforcement officer may cross the median of a divided highway when the officer has reasonable grounds to believe that a felony is being or has been committed, has personal knowledge that a vehicle is being operated at a speed or in a manner which is likely to endanger persons or property, or the officer has reasonable grounds to believe that the officer's presence is immediately required at a location which would necessitate crossing a median of a divided highway for this purpose. Fire department vehicles and public or private ambulances and rescue squad emergency service vehicles traveling in response to a fire alarm or other emergency call may cross the median of a divided highway when assistance is immediately required at a location which would necessitate the vehicle crossing a median of a divided highway for this purpose.
