Hurt in a Polaris Slingshot or trike crash in Las Vegas: motorcycle rules or car rules?

Last updated October 25, 2026.

For now, mostly motorcycle rules. Nevada law, as written today, counts any motor vehicle built to travel on no more than three wheels as a motorcycle, so a Slingshot-style three-wheeler and a trike are both motorcycles for most purposes. A 2023 law creating a separate "autocycle" category has been passed but takes effect only when the DMV Director gives formal notice. Fault and insurance work much as they do in any Las Vegas motorcycle accident claim.

Some of the three-wheelers on Las Vegas streets are rentals driven by visitors. When one crashes, the insurers quickly ask questions that do not come up with a car: did the driver need a motorcycle license, should anyone have been wearing a helmet, and which coverage rules apply to a vehicle that looks like a car but is registered like a motorcycle. This page answers those questions from the statutes as they read today.

How does Nevada classify three-wheelers, step by step?

Start with the motorcycle definition. In the vehicle registration chapter, a motorcycle is every motor vehicle designed to travel on not more than three wheels in contact with the ground, except electric bicycles, electric scooters, tractors and mopeds (NRS 482.070). The motorcycle chapter adds that it has a seat or saddle for the driver (NRS 486.041).
Check whether it is a trimobile. A trimobile is a three-wheeled motor vehicle with handlebars and a saddle seat; a motorcycle with a sidecar is not a trimobile (NRS 482.129, 486.057). Most trikes fit this description.
Check for an enclosed cab. A three-wheel vehicle, other than a trimobile, on which the driver and passengers ride within an enclosed cab is exempt from the helmet and eye-protection rule (NRS 486.231(5)).
Check whether the autocycle law is in effect. The 2023 law, Senate Bill 346 (2023 Statutes of Nevada, chapter 233), defines an "autocycle": three wheels, two in front and one behind, a steering wheel or handlebars, seat belts, foot pedals for brake and throttle, seats you do not straddle, and built to federal motorcycle safety standards (NRS 482.0107, 486.015). Section 6(3) of that law makes the autocycle sections effective only on the date the DMV Director notifies the Governor and the Director of the Legislative Counsel Bureau that the DMV has the resources to carry them out.
Apply the license and helmet rules for that category. The table below shows what the statute texts say under the current versions and under the autocycle versions.
Then handle the crash like any other. Report it, get the report, open the claims and watch the 2-year injury deadline (NRS 11.190(4)(e)). The step-by-step guide to what happens after a motorcycle crash in Las Vegas covers the claim itself.

License and helmet rules, as the texts read today

Vehicle	License needed (NRS 486.061)	Helmet (NRS 486.231)
Trike with handlebars and a saddle seat (trimobile)	A motorcycle license or a regular Nevada driver's license (486.061(1)(b))	Required; the enclosed-cab exception excludes trimobiles (486.231(2), (5))
Open three-wheeler with a steering wheel and seats, such as a Slingshot, under the current text	The text covers "a motorcycle, except a trimobile": a motorcycle license, a motorcycle endorsement or a motorcycle permit (486.061(1)(a))	Required unless the riders are within an enclosed cab (486.231(2), (5))
Three-wheeler with an enclosed cab, not a trimobile	Same as the row above under the current text	Not required (486.231(5))
Autocycle, once the 2023 law takes effect	A regular driver's license (486.061(1)(c), autocycle version)	Not required (486.231(6), autocycle version)

The Nevada DMV's own motorcycle page describes the rules a little differently. Its comparison table lists "Yes, Any Class" as the license for an "Other 3-Wheeler," and it says helmets are not required for three-wheeled vehicles with an enclosed cab and a steering wheel instead of handlebars. The page does not mention autocycles. Where the agency's summary and the statute's wording differ, the statute is the law, but expect both to be quoted after a crash. A visitor is also covered by the nonresident exception if at least 16 and authorized by their home state to drive a motorcycle (NRS 486.061(1)).

Why does the classification matter to an injury claim?

Mostly because the other side will use it. If the driver of a three-wheeler did not hold the license the insurer thinks was required, or no one was wearing a helmet, expect those facts to be raised. Neither one decides who caused the crash. Nevada's fault rule asks whose negligence caused the collision and reduces your recovery only by your share, barring it only if your share is greater than the defendants' combined (NRS 41.141(1), (2)).

The license point is covered in depth on our page about riding without a motorcycle endorsement. The helmet point, which tends to matter only for head and face injuries, is covered in how the helmet law affects a Nevada injury claim.

Classification also matters for insurance. Nevada requires insurers to offer uninsured and underinsured motorist coverage on a policy covering a passenger car or a motorcycle, and for that rule "motorcycle" has the meaning in NRS 482.070 (NRS 687B.145(2), (6)(b)). Under the current definition, that includes three-wheelers.

Who pays after a three-wheeler crash?

Source	When it can pay	Rule
The at-fault driver's liability insurance	Another driver caused the crash; minimum $25,000 per person and $50,000 per crash	NRS 485.185
The three-wheeler's own liability policy	Its driver caused or shared the crash; covers permissive drivers	NRS 485.185; 485.3091(1)(b)
Coverage a rental company provides	The three-wheeler was rented; Nevada expects at least 25/50/20 coverage for the renter and anyone driving with permission	NRS 482.305(1), (2)
Your UM and UIM coverage	The at-fault driver had no or too little insurance, or fled after contact	NRS 690B.020; 687B.145(2)
Medical payments coverage	If bought; insurers must offer at least $1,000	NRS 687B.145(3)

Riders often carry separate coverage for a motorcycle and a car, and either may have its own exclusions. Our page on what insurance covers a motorcycle rider in Nevada walks through each policy. For local police and courts, see our Las Vegas accident page.

What changes the answer

Whether the vehicle was rented. A rental company that did not provide the required coverage is jointly and severally liable with the renter (NRS 482.305(1)), but a company that did is generally protected from liability based only on ownership (49 U.S.C. 30106(a)). See how rental vehicle claims work.
Whether you were the passenger in a rented three-wheeler. NRS 482.305 gives a passenger in the rented vehicle no right of action against the rental company under that section, and its coverage need not cover the renter's liability to passengers (NRS 482.305(1), (3)). Passengers look to the drivers' policies and their own coverage; see motorcycle passenger injury claims.
Whether the autocycle law has taken effect. Once it does, an autocycle is excluded from the definition of motorcycle (NRS 482.070, 486.041, autocycle versions), needs only a regular license, and is exempt from the helmet rule.
The vehicle's design. Handlebars and a saddle seat make it a trimobile; a steering wheel and an enclosed cab change the helmet rule (NRS 482.129; 486.231(5)).
Who caused the crash. Several liability applies when more than one defendant is at fault and comparative negligence is raised: each pays his own share (NRS 41.141(4)).
Where it happened. The license and helmet rules apply on a highway ("upon a highway," NRS 486.061(1); "on a highway," NRS 486.231(2)). A crash in a parking lot raises different questions; see parking lot and garage crashes.

For example: a rented three-wheeler on Las Vegas Boulevard

Imagine two visitors, Jordan and Sam, who rent an open three-wheeler for an afternoon. Jordan drives; Sam rides beside him. Neither wears a helmet. Near Sahara Avenue, a pickup driver changes lanes without looking and clips their front wheel. Jordan breaks his wrist; Sam suffers a concussion and a fractured cheekbone. All figures and facts here are hypothetical.

The pickup driver's insurer responds with three arguments: Jordan had only a car license from his home state, nobody wore a helmet, and the vehicle was "basically a motorcycle." Each needs an answer. Under the current text, an open three-wheeler that is not a trimobile is treated as a motorcycle for licensing (NRS 486.061(1)(a)), and Jordan's home state did not authorize him to ride a motorcycle, so the license point may be technically right. But it does not explain the lane change. The fault question is still whose carelessness caused the crash (NRS 41.141).

The helmet point is different for each person. It has little to do with Jordan's wrist. It may be argued against Sam's head and face injuries, which is where medical opinions will matter. Sam's main claim runs against the pickup driver. If Jordan shared any fault, the rental company's coverage need not cover a renter's liability to a passenger (NRS 482.305(3)), so Jordan's own policy, if it reaches a rented three-wheeler, and Sam's own UM or UIM coverage become the places to look.

If the autocycle law were in effect and the vehicle met its definition, the license and helmet arguments would largely fall away (NRS 486.061(1)(c), 486.231(6), autocycle versions).

Common mistakes after a three-wheeler crash

Assuming car rules apply because it has a steering wheel. Under the current definitions, a three-wheeler is a motorcycle for most purposes (NRS 482.070).
Assuming the autocycle law is already in force. Its sections take effect only on the DMV Director's notice (2023 Statutes ch. 233, section 6(3)).
Losing the rental agreement. It shows who rented the vehicle, the coverage offered and who was allowed to drive.
Conceding fault because of a license or helmet issue. Those facts do not show who caused the collision.
Skipping your own policy. UM, UIM or medical payments coverage at home may apply; read the declarations page.

What to do this week

Photograph the vehicle: wheels, steering, seats, belts and whether it has any roof or enclosure.
Keep the rental agreement, receipt and any insurance you bought at the counter.
Request the crash report; see how to get a Las Vegas crash report.
Write down the license each driver held and the state that issued it.
Open claims with the other driver's insurer and the rental coverage, and notify your own insurer.
Save your helmet if you wore one; follow our list of evidence to keep after a motorcycle crash.
Mark 2 years from the crash for injuries and 3 years for property (NRS 11.190).

Frequently asked questions

Is a Slingshot legally a car or a motorcycle in Nevada?

Under the definitions in force today, a motor vehicle designed to travel on no more than three wheels is a motorcycle (NRS 482.070, 486.041). The 2023 autocycle law would move vehicles that meet its definition into a separate category once the DMV Director gives notice that it can carry the law out.

Has the autocycle law taken effect?

The NRS text, as checked for this page, still prints the autocycle sections as effective only on the date of that notice, and the DMV's motorcycle page does not mention autocycles. We did not find a published notice. Check the current status before relying on either version.

Do I need a helmet in a three-wheeler?

On a trike with handlebars and a saddle seat, yes (NRS 486.231(2), (5)). In a three-wheeler with an enclosed cab that is not a trimobile, no (NRS 486.231(5)). An open three-wheeler with a steering wheel falls under the general rule in the statute's current text, although the DMV's page describes the exemption by steering wheel and enclosed cab.

Can I still recover if I was not wearing one?

Yes. A missing helmet does not decide who caused the crash; it may be argued only on injuries a helmet could have affected. Your recovery is reduced by your share of fault, if any (NRS 41.141).

I was a visitor with a car license. Was I allowed to drive the rental?

For a trimobile, a regular driver's license works (NRS 486.061(1)(b)). For other three-wheelers, the current statute text requires motorcycle authority, and the nonresident exception covers visitors whose home state lets them drive a motorcycle (NRS 486.061(1)). The DMV's table lists any class for other three-wheelers. For the visitor side of a claim, see crashes while visiting Las Vegas.

Does motorcycle insurance or car insurance cover a three-wheeler?

Whichever policy lists that vehicle. Nevada requires every registered motor vehicle except a moped to carry at least 25/50/20 liability coverage (NRS 485.185), and the DMV's table lists liability insurance as required for motorcycles, trimobiles and other three-wheelers.
