Highway Width & Height Limits
As shown on the map and in the illustrations below, there is good reason tiny homes on wheels are limited to 13’ 6” in height and 8’ 6” in width. However, with state-issued permits, much larger tiny homes on skids can be transported from point of assembly to building site. Low clearances, restricted routes, and state permitting agency phone numbers and websites are all listed in the Rand McNally Deluxe Motor Carrier’s Road Atlas (available on Amazon).
