a

Vehicles propelled by an internal combustion engine, electrical means or both (see SAE J551/1 for definition)

b

Motorboats propelled by an internal combustion engine, electrical means or both

NOTE-For the purposes of this publication, motorboats are considered to be a subset of vehicles unless specifically mentioned to the contrary.
