A crash casualty may have a spinal injury and is not exposed to fire or another immediate danger. What is the safest general approach for an untrained bystander?

1. Move the person into a sitting position to make conversation easier
2. Avoid unnecessary movement, call emergency services, and monitor the person
3. Pull the person by the arms to the roadside even though the scene is secure
4. Ask the person to walk to test whether the spine is injured
