How far from stop sign must a car park in Iowa?
In general it is 15 feet, a fire hydrant25 feet-just remember this with the fire hydrant, IF you are parked close to it and the fire company is using it and their hose, axe, saw, or fire truck bangs into it it's on you- so don't park close to keep your car from damage. With the stop sign, you could be blocking the view of another driver who needs to see the cross traffic before pulling out, also if a large truck has to make a right turn and you are too close to the corner the back of the truck could smash the front of your car unknowingly and keep on going, that would make you not look so good when the police wright up the accident report.
