(a) Whenever any highway has been divided into two roadways by an intervening space, or by a physical barrier, or a clearly indicated dividing section so constructed as to impede vehicular traffic, every vehicle shall be driven only upon the right-hand roadway, and no vehicle shall be driven over, across, or within any dividing space, barrier, or section, except through an opening, crossover, or intersection established by public authority. This section does not prohibit the occupancy of the dividing space, barrier, or section for the purpose of an emergency stop, or in compliance with an order of a police officer.
(b) Except as otherwise provided in this division, whoever violates this section is guilty of a minor misdemeanor. If, within one year of the offense, the offender previously has been convicted of or pleaded guilty to one predicate motor vehicle or traffic offense, whoever violates this section is guilty of a misdemeanor of the fourth degree. If, within one year of the offense, the offender previously has been convicted of two or more predicate motor vehicle or traffic offenses, whoever violates this section is guilty of a misdemeanor of the third degree.
(c) If the offender commits the offense while distracted and the distracting activity is a contributing factor to the commission of the offense, the offender is subject to the additional fine established under § 408.02.
