Many areas you would be in the right unless its at night or on a main highway. I pulled a non-folding 14 ft'er home a couple of years ago and had to sneak onto a 4 lane for an hour or so. Luckily no traffic.
The 2 land road from the owners house was a problem, no shoulders and mailboxes at the pavement edge. We had to pull into driveways when we met people coming the other way.
