If a school bus catches fire during an evacuation, in what direction should the driver lead students to reach a safe place?

AAMVA CDL Manual, Section 10.3.2 (Evacuation Procedures), p. 10-6

Smoke inhalation, not the fire itself, is often the greater immediate threat to evacuating students. Leading students upwind keeps toxic smoke moving away from them rather than into the group as they move to safety.
