would concrete bust right off

[64auto]

I had a roll off trash container brought in for my garage build. On one side of my driveway is a concrete slap where we park the cars. I have a piece of iron drove in the ground so none of the trucks would run over the cornor of the slab. Well this driver pulls up the iron and goes on over the slab. Would the slap have cracked when he drove over it or is this something that can happen later on?

Concrete breaks right now.

True it may have a break in it that will take awhile to show up. I had 10 yards of sand fill delivered for a drive apron. I asked the driver to dump it on the present drive saying I would push it into the formed area with my garden tractor with blade. Nope! He backs right in off the edge of the drive to dump. I didn't see the cracks in the old concrete for a good 6 months and now 7 years later its an entire project to repair the cracked out section. A little unsightly but it will have to wait as there are all kinds of projects ahead of it.

A concrete truck drove over part of the drive going to my shop that had a drain pipe under it and it cracked all the way across above the pipe. He was delivering concrete for my shop addition.
