A driver is choosing whether to evacuate after a minor fender-bender on a wide shoulder. There is no fire, no spill, no train hazard, and students are safer inside than outside in traffic. What is the best decision?

1. Do not evacuate automatically; keep students protected and follow emergency reporting procedures unless conditions change
2. Evacuate every crash scene no matter what
3. Send students to stand behind the bus to wait
4. Let students walk home from the shoulder
