It shall also be the duty of all peace officers, including municipal law enforcement officers and members of the said highway safety patrol, to investigate any alleged violation of this chapter reported to them and to proceed according to law.

On and after May 2, 1958, any person operating a motor vehicle upon the public highways of this state who has not complied with the provisions of this chapter shall be arrested by any officer authorized to make arrests, and tried, and, if convicted, shall be guilty of a misdemeanor for each separate offense and shall be fined as now provided by law, and each such illegal operation of a motor vehicle upon the public highways of this state shall constitute a separate offense.

Penalties shall be assessed on the ad valorem taxes due at the rate of five percent (5%) for the first fifteen (15) days of delinquency, or part thereof, and five percent (5%) for each additional thirty-day period of delinquency, or part thereof, not to exceed a maximum penalty of twenty-five percent (25%).
