When possible, the AAMVA CDL Manual recommends assigning two responsible, older student assistants to each emergency exit before an emergency ever happens. What is their role?

AAMVA CDL Manual, Section 10.3.2 – Evacuation Procedures (Be Prepared and Plan Ahead), p. 10-6

In a real emergency, a single driver cannot physically help every student at every exit at once. Pre-assigning older students to each exit means help is already in place the moment an evacuation starts, which can shave critical seconds off getting everyone out safely.
