What action is required when approaching a steady yellow (amber / feu jaune-orange) traffic light in DR Congo?

1. Stop before the stop line, unless the vehicle is so close that stopping safely is impossible without risking a rear-end collision
2. Accelerate immediately to cross the intersection before the red light appears
3. Proceed normally without stopping, as yellow is merely an informational light
4. Come to an emergency stop by applying maximum handbrake force immediately
