RV rental laws & regulations in Tennessee
A plain-language guide to the rules that decide whether you can pick up, drive, and camp a rented RV, boat, or off-road vehicle in Tennessee. Written for first-time renters and for visitors from outside the US — where rules change at every state line.
In the United States, vehicle and camping rules are set state by state, not nationally. The items below are the ones most likely to cost you a pickup or a fine in Tennessee. Each carries the official source it came from and the date we last checked it.

Motorhomes & RVs — Tennessee
CDL rules start at 26,001 lbs — below that the standard license applies
Tennessee defines a commercial motor vehicle as one over 26,001 lbs GVWR (or hazmat/16+ passengers), and its official list of 'Vehicles that do not Require a Commercial Driver License' explicitly includes 'Recreational vehicles such as a motorhome'; a regular Class D license covers personal motorhomes under 26,001 lbs.

0.08% BAC; the open container ban applies to the driver only
Tennessee sets the DUI threshold at 0.08% BAC (TCA §55-10-401), but its open container law reaches only the person behind the wheel: no driver may consume or possess an open alcoholic beverage while operating a motor vehicle. Tennessee is one of the few states that does not extend the ban to the whole passenger area, so passengers are not covered by the state rule. Cities and counties may still prohibit passenger open containers by local ordinance, so keep anything open stowed while underway.

Great Smoky Mts NP: rig length caps are set per campsite
Great Smoky Mountains National Park sets RV length limits site by site rather than campground-wide, and each site's maximum is published on the federal reservation system. Cades Cove has 58 RV-capable sites running from 20 ft up to 42 ft — most commonly 24 ft or 35 ft — so a 30 ft rig is welcome on many of them. Check the individual site's listed maximum length before booking rather than assuming a single park-wide number.

Frequently asked
Do foreign visitors need a special license to rent an RV in Tennessee?
Visitors from outside the US can usually drive a standard rental motorhome on a valid home-country license under US reciprocity. Tennessee's age and weight limits still apply, and a special non-commercial license may be needed for the largest rigs. Confirm with TN Driver Services before you travel.
