Been there done that,not a good feeling I needed toilet paper allot of it!!!

I had this same thing happen once on a job...You know what we had to do about it??...I was pumping an ICF wall,And had to fold up back the pump up to the truck re-set and empty it,Luckily I could reach the wall from where the truck wedged itself agianst the tree!!

Somebody knew that 4 feet of uncompacted fill dirt was used to make that driveway.  Would be a good idea to tell the mixer driver. Dumba**

Here are a couple from my job the other morning - front brake locked up. Driver dislocated his elbow - very lucky!

That'll buff right out.
