I had a new 4" deep concrete driveway poured last week. How long should I
wait before I should drive my sedan on it? What about allowing a small
delivery truck (UPS/FedEx) to pull in?


Concrete fully cures in about a month, but you can drive on it after a
day. Keep your drive watered down for a week or two. Pouring
concrete is more of an art than a science. Good luck.
