NCDOT Route Survey (PF-16A) for 16 ft Wide Mobile Home Moves

Updated 2026-10-28. Last verified against the sources below: October 28, 2026. General information, not legal advice; rules and fees change, so it may be out of date. The issuing office's current rules control.

For 16 ft wide mobile and modular home moves, NCDOT wants a Route Survey Form (PF-16A) from both the transporter and the certified escort driver before the application is complete, on two kinds of roads^ST-1:

Primary routes with restrictions shown on the NC Truck Network map (linked from the Permit Unit page^NCDOT), and
All secondary routes west of Cleveland, Lincoln, Catawba, Iredell, Davie, Forsyth and Rockingham counties^ST-1.

Does it apply to me?

Only if your widest section is 16 ft. 12 and 14 ft homes aren't covered by this requirement in ST-1. If you're moving a 16 ft home in the mountains or foothills on state-maintained secondary ("SR") roads, plan on it.

Correction: an earlier version of our regional guide said every mobile home move on western secondary roads needed a PF-16A. NCDOT's current publication ties it to 16 ft wide homes.

What it means for you

Someone has to drive the route first and sign off on curves, grades, bridges and clearances, so add a few days to the schedule.
It needs a certified escort driver, which ties into escort costs in the width and escort guide.
Tight gravel drives and steep turns are where moves stall. Walk the last mile with your contractor and trim limbs before move day.

Questions for your transporter

Is my home 16 ft at its widest, and does my route need a PF-16A?
Are the survey and escort time in the quote?
If the survey finds a problem, what's plan B: re-route, wait, or extra equipment?
