The Missouri governor signed a bill into law June 1 that will take effect Aug. 28 defining an autocycle.
From the full text, new portions are in bold:
(2) "Autocycle", a three-wheeled motor vehicle which the drivers and passengers ride in a partially or completely enclosed nonstraddle seating area, that is designed to be controlled with a steering wheel and pedals, and that has met applicable Department of Transportation National Highway Traffic Safety Administration requirements or federal motorcycle safety standards;
The new law also clarifies what a "Motortricycle" is:
(39) "Motortricycle", a motor vehicle upon which the operator straddles or sits astride that is designed to be controlled by handle bars and is operated on three wheels, including a motorcycle while operated with any conveyance, temporary or otherwise, requiring the use of a third wheel. A motortricycle shall not be included in the definition of all-terrain vehicle;
And if you have one currently registered:
13 2. Notwithstanding any other provision of law, the registrationof any autocycle registered as a motorcycle or motortricycle prior toAugust 28, 2018, shall remain in effect until the expiration of the registration period for such vehicle at which time the owner shall be required to renew the motor vehicle's registration under the autocycle classification and pay the appropriate registration fee
Mandatory helmet use is not required on autocycles. The word "shall" changed to "may not":
2. Notwithstanding subsection 2 of section 302.020, a person operating orriding in an autocycle [shall] may not be required to wear protective headgear
So it appears the Slingshot, Stallion, T-Rex and such are now under the heading of "Autocycle"
in Missouri and no helmet is needed. Conversions, VW and other trikes you sit astride and steer with handlebars
and are open are still motorcycles (or more specifically "Motortricycles") and helmets are required in this state.
