You must be 21 years old to drive in intrastate commerce and 18 to drive in interstate commerce. True or False?

Answer: B — False

The statement is false because the age requirements for driving a commercial vehicle differ based on the type of commerce involved. To operate a commercial motor vehicle (CMV) in interstate commerce, a driver must be at least 21 years old. This requirement applies universally across all states. For intrastate commerce, however, regulations can vary by state. Many states permit drivers as young as 18 to operate CMVs within state borders, which is why this statement does not hold true. It incorrectly conflates the age requirement for interstate commerce with the rules that govern intrastate operations. Therefore, the correct understanding is that at 18, one may drive commercially within the state, while 21 is the minimum age for interstate driving.
