Turtarriers are concrete blocks placed at the back of parking spaces. Often they are yellow or gray, but they can come in any color. Sometimes they are also referred to as "parking barriers" or "parking blocks" but these are both improper terms.
When I pull my car into the parking space I know I have gone too far if I can feel the wheel come into contact with the turtarrier.
