Are drivers responsible for their passengers buckling up?
Answer: A — Only if passengers are from five years of age to sixteen years.
Drivers are responsible for making sure their passengers from five to sixteen years old are buckled up. This answer is correct because it covers the legal responsibility of drivers to ensure the safety of minors in their vehicle. The other options are incorrect because they either place the responsibility on passengers over a certain age or limit the responsibility to specific seating positions. However, in most places, drivers are responsible for all their passengers regardless of age or seating position.
