A bus is involved in a minor roadside crash. There is no fire, no fuel smell, no hazardous spill, no traffic threat, and students are calm. What does the CDL evacuation guidance suggest?

1. Keeping students on the bus may be safer if remaining onboard does not expose them to unnecessary risk
2. Evacuate automatically in every crash regardless of outside hazards
3. Let students scatter to call parents
4. Move students behind the bus in the traffic lane
