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

Hi,
I had a concrete pad poured in my back yard to park 7000 lbs. 5th wheel
trailer and 3/4 ton PU truck. I parked both after 10 days since pad was
poured. Nothing bad happened. Really concrete cures LONG time; ~
100 years, gets harder and harder with time.
