Concrete testing (compressive strength) I have seen is done at 2-7 days
after pour, and again at 28 days after pour.

Measurements I have seen showed about 70% strength after 2-3 days and
100% strength at 28 days.

Of course the type of concrete and the weather conditions will cause
variations.

I would wait a week to drive on it.

I had a new concrete driveway poured about 5 days ago . I waited 24
hours then have been misting it with a hose 3 times a day ( except
for rain of course ) . The weather has been overcast more or less and
the temps have been ranging for 50-68 degrees F. How long should I
wait before drive on it with a full size pickup truck ( unloaded ) . I
want to use the driveway ASAP but don't want to take any unessary risk
.
