(c) Whenever any roadway is clearly marked for two or more lanes of traffic moving in the same direction, no person driving a motor vehicle in the lane or lanes other than the extreme right lane shall travel at a speed that is 5 miles per hour or more below the maximum stated speed, e.g., below 30 miles per hour in a 35-mile-per-hour speed limit zone or below 40 miles per hour in a 45-mile-per-hour speed limit zone, except when otherwise directed by a police officer or any other persons authorized to direct, control, or regulate traffic, or when a reduced speed is necessary for safe operation, or in compliance with the law.
(d) On any street or highway or portions thereof on which parking is prohibited during the hours specified, during the morning peak traffic or afternoon peak traffic hours, or both, no person shall drive, move, or tow, nor shall a registered owner knowingly cause or permit any person to drive, move, or tow, during those hours on such street or highway or portions thereof, any vehicle that cannot maintain a speed equal to the maximum stated speed, less 5 miles per hour, for such street or highway or portions thereof; provided that the foregoing provisions shall have no force and effect on public holidays as defined in § 15-2.19.
