Like many cities across the nation, the City of Saginaw, Michigan, has used tire chalking — the technique of marking a parked car’s tire with chalk to determine how long it has been stationary. When an officer returns to a car he or she knows was chalked outside the time limit permitted for parking, and sees chalk on the tire that indicates the car has likely not moved, a citation is issued.
