Until what point should a charter bus driver generally keep riders from boarding?
Correct answer: C – Until departure time
A charter bus driver should generally wait until departure time before allowing riders to board. Keeping the bus closed earlier helps protect it from theft or vandalism. The timing is not based on whether all passengers have arrived, whether baggage loading is complete, or whether a dispatcher has issued a boarding instruction.
