Any municipality may pass, and by proper penalties enforce, ordinances for these purposes, and by such ordinances:

(2) require the payment of inspection fees, but such fees shall not exceed the amount of 50 cents for any one inspection, or $1 for any one year;
(3) provide free inspections as often as the owner desires between compulsory inspection periods;

(5) prohibit the operation on the public streets of such municipality of any motor vehicle which shall not have been submitted for inspection within a reasonable time after notice of such required inspection shall have been given to the owner of such motor vehicle or the owner's agent, or any motor vehicle which shall be found to be in a faulty or unsafe condition or in violation of any city ordinance or state law, and now having a proper inspection certificate properly displayed.
(b) No such inspection shall be required of the owner of a vehicle who is not a resident of the municipality operating and maintaining the motor vehicle testing station.
