Ownership & compliance
Is the T-REX street legal in Arizona?
In Arizona, the Motor Vehicle Division (MVD) of the Arizona Department of Transportation titles, registers, and licenses drivers. Arizona recognizes an “autocycle” class for certain three-wheeled vehicles, which can affect the licence and helmet requirement. Confirm how your T-REX is classified with the Arizona MVD before purchase.
How three-wheeled vehicles are classified
The Campagna T-REX is homologated for road use and titled as a three-wheeled motor vehicle. Across North America, a three-wheeled vehicle is generally registered as a motorcycle, and many U.S. states have added an “autocycle” class for cars-on-three-wheels like the T-REX. That classification is what determines whether you need a motorcycle endorsement, a standard driver’s licence, or a helmet — and because it is set locally, the answer depends on where you live and ride.
Licence and helmet
Where a three-wheeler is treated as a motorcycle, a motorcycle endorsement and a helmet are often required. Where an “autocycle” class applies, a standard driver’s licence may be enough and a helmet may be optional. Always confirm the current rule with the authority below.
