ramp over 1 foot high earth berm

[delagina]

I only have 1 foot high berm with 1 foot crown width also. if I use 10% slope ramp, is this ok?
I'm confused about ground clearance of truck.
I don't want to unnecessarily widen the berm crown with at the ramp location though.

Depends on the truck. You should have local road engineering standards that include standard details.

There are designs for "calming" bumps/humps/devices . . . see example:
