A disruptive rider is creating a disturbance, and the next available location is a dark isolated shoulder. What should the driver consider first?

1. Do not discharge the rider where it would be unsafe; continue to a safer scheduled or well-lit location if necessary
2. Discharge the rider immediately because disruption always overrides rider safety
3. Leave the rider on the shoulder if other passengers approve
4. Open the door and let the rider decide whether the location is safe
