What speeds can a moped NOT be capable of?

• A. More than 30 mph on level ground.
• B. If combustion, engine larger than 50cc.
• C. Both A and B.
• D. None of the above.

Answer: (C)

Mopeds have two clear limits: they can’t be capable of more than 30 mph on level ground, and if they use a combustion engine, the engine must be 50cc or smaller. So a vehicle that can exceed 30 mph on level ground would not fit the moped definition, and a combustion-powered one with more than 50cc isn’t a moped either. Because both of these restrictions apply, the option that includes both limits is the right choice. The other options either miss one limit or imply there are no limits at all.
