Does a retaining wall need a different design if it also holds back a driveway?

Yes, genuinely — a retaining wall supporting a driveway needs to account for vehicle loading (surcharge load) on top of the normal soil pressure, which a wall only retaining garden soil doesn’t need to consider.

Flagging that a driveway sits above or near the wall to your engineer ensures this genuine extra load is properly designed for.
