First thing it to make sure your rig is well set up and you are comfortable controlling it so these types of passes are a NON issue.
We pull a 35ft TT 60ft overall and when a semi, or double passes us on the left I notice a very slight push but if it moves me even 6 inches anywhere I'd be very suprised. Same when we pass a semi. Get your WD properly set up, and a sway control suitable for your rig and passing or being passed will be a non issue.
I agree that my rig doesn't actually move much but the push is felt. I was prepared for it to push the opposite way from past experience but with my new set up it was different. I don't have an issue with it, just answering the OP's question.
