## Decision flowchart for vehicles

1. Is it a motor vehicle? §85.1703: A vehicle which is self-propelled and capable of transporting a person or persons or any material or any permanently or temporarily affixed apparatus shall be deemed a motor vehicle, unless any one or more of the criteria set forth below are met, in which case the vehicle shall be deemed not a motor vehicle:



### ! The vehicle cannot exceed a maximum speed of 25 miles per hour over level, paved surfaces; or



### ! The vehicle lacks features customarily associated with safe and practical street or highway use, such features including, but not being limited to, a reverse gear (except in the case of motorcycles), a differential, or safety features required by state and/or federal law; or



### ! The vehicle exhibits features which render its use on a street or highway unsaf e, impractical, or highly unlikely, such features including, but not being limited to, tracked road contact means, an inordinate size, or features ordinarily associated with military combat or tactical vehicles such as armor and/or
weaponry. 

## -If yes, 40 CFR parts 85 and 86 apply. -If not, see #2.

2. Is it an off-highway motorcycle or snowmobile? §1051.801: Off-highway motorcycle means a two-wheeled vehicle with a nonroad engine and a seat (excluding marine vessels and aircraft). (Note: highway motorcycles are regulated under 40 CFR part 86.) §1051.801: Snowmobile means a vehicle designed to operate outdoors only over snow-covered ground, with a maximum width of 1.5 meters or less. 

## -If yes, part 1051 applies. Note that §§1051.605 and 1051.610 allow for vehicles or engines to be certified under part 86 or 1048. Note also that diesel-fueled engines used with off-highway motorcycles or snowmobiles may be certified under part 89 or 1039 under the provisions of §1051.5. -If not, see #3.

3. Is it an offroad utility vehicle? §1051.801: Offroad utility vehicle means a nonroad vehicle that has four or more wheels, seating for two or more persons, is designed for operation over rough terrain, and has either a rear payload capacity of 350 pounds or more or seating for six or more passengers. Vehicles intended primarily for recreational purposes that are not capable of transporting six passengers (such as dune buggies) are not offroad utility vehicles. (Note: §1051.1(a) specifies that some offroad utility vehicles are required to meet the requirements that apply for all-terrain vehicles.) 

## -If yes, see #4. -If not, see #5.

4. Is the offroad utility vehicle subject to part 1051? §1051.1(a)(4) Offroad utility vehicles with engines with displacement less than or equal to 1000 cc, maximum engine power less than or equal to 30 kW, and maximum vehicle speed higher than 25 miles per hour. Offroad utility vehicles that are subject to this part are subject to the same requirements as ATVs. This means that any requirement that applies to ATVs also applies to these offroad utility vehicles, without regard to whether the regulatory language mentions offroad utility vehicles. 

## -If yes, part 1051 applies. Note that §§1051.605 and 1051.610 allow for vehicles or engines to be certified under part 86 or 1048. Note also that diesel-fueled engines used with offroad utility vehicles may be certified under part 89 or 1039 under the provisions of §1051.5. -If not, see #6.

5. Is it an all-terrain vehicle? §1051.801: All-terrain vehicle means a land-based or amphibious nonroad vehicle that meets either of the following criteria: (1) Vehicles designed to travel on four low pressure tires, having a seat designed to be straddled by the operator and handlebars for steering controls, and intended for use by a single operator and no other passenge rs are all-terrain vehicles. (2) Other all-terrain vehicles have three or more wheels and one or more seats, are designed for operation over rough terrain, are intended primarily for transportation, and have a maximum vehicle speed of 25 miles per hour or higher. Golf carts generally do not meet these criteria since they are generally not designed for operation over rough terrain. NOTE: Amphibious vehicle means a vehicle with wheels or tracks that is designed primarily for operation on land and secondarily for operation in water. 

## -If yes, part 1051 applies. Note that §§1051.605 and 1051.610 allow for vehicles or engines to be certified under part 86 or 1048. Note also that diesel-fueled engines used with all-terrain vehicles may be certified under part 89 or 1039 under the provisions of §1051.5. -If not, see #6.

6. Does it have a spark-ignition engine? §1054.801: Spark-ignition means relating to a gasoline-fueled engine or any other type of engine with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark-ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. 

## -If yes, see #7. -If not, it is subject to standards for diesel engines (marine, locomotive, or other land-based nonroad).

7. Is it a marine vessel? §1054.801: Marine vessel has the meaning given in 1 U.S.C. 3, except that it does not include amphibious vehicles [See #5]. The definition in 1 U.S.C. 3 very broadly includes every craft capable of being usedas a means of transportation
on water. 

## -If yes, part 1045 applies. -If not, the engine is subject to standards for Small SI or Large SI engines, depending on the maximum engine power and total displacement.
