Answer: 200 ft (or even less, or even none)
Step-by-step explanation:
First of all we have to remember that to pass a car, the line on the road has to be intermittent. Passing a car while a continuous line lies beneath us is a sign of "passing cars is forbidden " most of citizens forgive this simple rule. And even if you have the chance of passing a car, do it carefully, at a distance even longer than 300 ft. You never know if somones´s driving a sport car at 160mph.
