Arizona Golf Cart and Neighborhood Electric Vehicle Road Rules

Start with the definitions, because Arizona's two low-speed categories are not interchangeable. A.R.S. § 28-101(37) defines a "golf cart" as a motor vehicle with at least three wheels on the ground, an unladen weight under 1,800 pounds, designed to be and operated at not more than 25 mph, and designed to carry not more than four people including the driver. Nothing in that definition requires electric power, so a gas cart is still a golf cart. A.R.S. § 28-101(55) defines a "neighborhood electric vehicle" much more tightly: it must be self-propelled and electrically powered, emission free, have at least four wheels in contact with the ground, and comply with the federal low-speed vehicle definition and standards at 49 C.F.R. §§ 571.3(b) and 571.500 unless excepted or exempted under federal law. Those federal standards are what bring seat belts, lights, mirrors, a windshield and a VIN into it. A typical course cart is not an NEV; a street-package cart built to FMVSS 500 is.

The class you fall into decides which operating rules apply. A.R.S. § 28-966 is written for neighborhood electric vehicles, neighborhood electric shuttles, motorized quadricycles and neighborhood occupantless electric vehicles, and it does not mention golf carts at all. For an NEV, subsection A caps operating speed at 25 mph. Subsection B bars it from any highway posted above 35 mph, while expressly allowing it to cross such a highway at an intersection, which is what lets an NEV get from one 35 mph neighborhood to the next across a six-lane arterial. Subsection C requires "a notice of the operational restrictions applying to the vehicle permanently attached to or painted on the vehicle in a location that is in clear view of the driver", a placard requirement with no counterpart for golf carts. Subsection G defines highway there as "a street or roadway", and the same subsection A caps a motorized quadricycle at 15 mph.

A plain golf cart is governed instead by the general law applying to any motor vehicle. That starts with registration. A.R.S. § 28-2153(A) forbids operating, moving or leaving standing on a highway an unregistered motor vehicle, and subsection D(7) exempts only "a golf cart used in the operation of a golf course or only incidentally operated or moved on a highway". Crossing a street from the eighteenth green to the clubhouse lot is incidental; driving to the grocery store three mornings a week is not, and that cart needs a title, registration and plate. Subsection D contains no equivalent exemption for a neighborhood electric vehicle, so an NEV is registered from the start.

A driver license is required for both. A.R.S. § 28-3151(A) prohibits driving "a motor vehicle or vehicle combination on a highway without a valid driver license", and both classes are motor vehicles: § 28-101(52)(a)(i) defines a motor vehicle as a self-propelled vehicle, and the exclusion list in § 28-101(52)(b), which runs from motorized wheelchairs and electric bicycles to electric standup scooters and motorized skateboards, names neither golf carts nor NEVs. An unlicensed teenager may not legally drive the family cart on a public street anywhere in Arizona, inside a retirement community or outside one.

Equipment rules apply too. A.R.S. § 28-921(A) makes it unlawful to drive or move, or for an owner knowingly to permit the moving of, a vehicle lacking the lamps and other equipment required by Title 28, Chapter 3, Article 16, and § 28-921(C) exempts only farm and road machinery being incidentally moved and Arizona Game and Fish night patrol vehicles. Golf carts are not on that list, which is the practical obstacle to putting a bare course cart on a street.

The one place Arizona bends its road rules for these vehicles is A.R.S. § 28-721(C), and it is drawn very narrowly. In an age restricted community located in an unincorporated area of a county with a population of more than three million persons, a person may drive a golf cart or a neighborhood electric vehicle on a paved shoulder adjacent to a roadway, or as close as practicable to the right-hand curb or edge of a paved roadway where there is no delineated shoulder. Maricopa County is the only Arizona county above three million people, so the privilege reaches unincorporated age restricted communities such as Sun City, Sun City West and Sun Lakes and stops there. Green Valley, the large retirement community south of Tucson, sits in Pima County and is well under the population threshold, so its cart drivers get no shoulder privilege from this subsection. A.R.S. § 28-777 attaches a duty to the privilege: a person driving a golf cart or NEV under § 28-721(C) "shall yield the right-of-way to a vehicle that is traveling in the same direction and that is intending to turn to the right".

Outside that shoulder rule a cart or NEV in the roadway is a slow vehicle: § 28-721(B) keeps it in the right-hand lane or as close as practicable to the right-hand curb, § 28-704(A) forbids driving so slowly as to impede the normal and reasonable movement of traffic, and § 28-704(C) requires a driver on a two-lane highway where passing is unsafe to pull off at the nearest turnout once five or more vehicles have queued behind.

What Arizona does not have is a local opt-in. A.R.S. § 28-627(A) enumerates the traffic powers a city, town or county may exercise, reaching off-highway vehicle access routes in paragraph 13 and electric bicycles and standup scooters in paragraph 14, with a catch-all in paragraph 12 confined to regulations "specifically authorized by this chapter or chapter 4 or 5". Golf carts appear nowhere in it, and Title 28 has no cart street-designation section, so an Arizona municipality cannot vote to open a road to golf carts the way some states allow. The state rules above apply directly, and a community's own cart paths are a private-property matter rather than a traffic ordinance.

Enforcement follows the class and the chapter. § 28-2153(D)(7) triggers § 28-2532(A), a civil penalty of three hundred dollars; § 28-2532(B) requires the court to dismiss the action if the driver obtains the appropriate registration or plates afterwards. 02 surcharges added under § 28-121(C). The same civil treatment covers a failure to yield to a right-turning vehicle under § 28-777 and the slow-vehicle duties in §§ 28-704 and 28-721. Driving either vehicle on a public street without a licence is charged under § 28-3151, which sits in Chapter 8; § 28-121(A) excludes Chapter 8 from the misdemeanor default and § 28-121(B) makes the violation a civil traffic violation unless the licensing statute provides otherwise.

Equipment failures are charged through § 28-921(A), and that section makes the owner who knowingly permits the vehicle to be moved liable alongside the driver, which matters where a household cart is shared.
