According to the AAMVA CDL Manual's route unloading procedure, what must students do when the bus stops at a designated unloading area?

AAMVA CDL Manual, Section 10.2.3 – Unloading Procedures on the Route, p. 10-4 (July 2017 revision); knowledge topic required under 49 CFR §383.123(a)(1)

Most student injuries and deaths happen getting on or off the bus, not while riding in it, so controlling exactly when students move is a core safety control. Keeping students seated until told to exit gives the driver a clear window to finish checking mirrors and confirm the area is safe before anyone starts moving toward the door.
