A driver has reached 4 hours 20 minutes of continuous driving and is approaching a known congestion area. What is the best planning decision?

1. Continue into the congestion and hope to find a stop after 4.5 hours
2. Plan a safe stop before exceeding 4.5 hours of driving
3. Switch the tachograph to break while still driving slowly in traffic
4. Use hazard warning lights so the rule does not apply
