Rhode Island has joined dozens of other states in enacting rules classifying the autocycle and allowing drivers to operate one without a motorcycle license or endorsement. Maryland also has new rules that it began publicizing Monday.
Autocycles have three wheels, typically two in the back and one in the front. They also have steering wheels, foot pedals and are sometimes enclosed. Some are designed for fun and others for fuel efficiency; they range in price from $6,800 to as much as $65,000.
John Gablinske, 60, has been riding motorcycles for four decades, but his advancing age and the loss of some of his fingers left him looking for an alternative. The Bristol, Rhode Island, resident found what he was looking for this year at a Massachusetts store selling the Polaris Slingshot.
He describes the two-seat, three-wheeled convertible as like an "adult go-kart," but one he can ride with his wife on roads and highways at normal speeds.
"It gives me the feeling of openness without having to ride a motorcycle," Gablinske said. "I was all excited. Then I went to the registry and come to find out, they were illegal in Rhode Island."
Manufacturers, including Medina, Minnesota-based Polaris Industries, have spent years lobbying states to legalize the vehicles and distinguish them from motorcycles so it's easier for consumers to get one without knowing how to drive a two-wheeled vehicle. They've also pushed to exempt riders of autocycles from having to wear a helmet, especially if the vehicle has a hard top.
Among the most vocal lobbyists has been a company that hasn't yet rolled out any of its futuristic-looking vehicles: Phoenix-based Elio Motors. Touting the fuel efficiency of its prototypes, the company has already made more than 55,000 pre-sale reservations. After years of delays, it plans to begin mass assembly of its vehicles at a Shreveport, Louisiana, plant next year.
"You get your government stuff done first," said Joel Sheltrown, Elio's vice president of governmental affairs and a former Michigan legislator.
Beginning in 2014 with his home state of Michigan, Sheltrown has worked from Vermont to Idaho, persuading state governments to pass legislation allowing the three-wheelers on the road.
Many of them have, but laws vary from state to state. Some require seat belts, air bags and roll cages. Others require helmets but make exceptions based on the age of the driver and whether the vehicle's cab is open or closed.
In Maryland, where the state transportation agency held an event Monday to publicize new rules, helmets are required with a convertible but not with a hard top. The rules took effect last month.
Rhode Island's autocycle law was enacted last month.
"Rhode Island did what I needed them to do, which is to exempt from helmets and exempt from the (motorcycle) endorsement requirements," Sheltrown said.
Gablinske wasted no time and is already riding his autocycle around his coastal town.
"It's so exotic," he said. "You're like a celebrity everywhere you go."
