I know this will vary based on all sorts of factors, but is there a general guideline on how long it takes a newly poured driveway to cure enough to drive over (but not park on)?

The internet has widely varying answers so I thought I'd ask the internet. :P

The driveway will be 6" deep curing in nice spring weather (daily highs mid 60s, lows in the low 50s). My vehicles range from 3600 lbs to 9000 lbs.

I will certainly follow the installer's instructions, but I want an idea before I start of what I'm getting myself into. Thanks!
