The speedometer or odometer which records the number of miles traveled by a vehicle having a 6,000-mile registration shall be kept in working condition at all times during the registration period. The highway patrol, motor carrier inspection bureau, or any law enforcement officer shall have authority to inspect the readings of the speedometer or odometer and to inspect the vehicle to ensure that the speedometer or odometer is properly connected and in good working condition. The operator of this vehicle shall keep at all times in the vehicle a log reciting the date, the towns traveled in, and the distance operated on each trip. Anyone securing a 6,000-mile registration and not having the speedometer or odometer connected and in good working condition or not having the log in the vehicle shall have the vehicle registration suspended and the registration shall not be reinstated until the difference between the 6,000-mile and the regular registration fee on the vehicle is paid.
