Are the steering wheels to be in locked position on dollies with swiveling platforms?

The manual did not specify that the wheels needed to be locked. In my case, I would have to tie the steering wheel down inside the cabin. I just tie a white rag around the top of my steering wheel so I can see it in the rear view camera and check during turns to see that it doesn't move too far.
