What is the safe procedure for a heavy truck driver before overtaking a long vehicle on a two-lane road?

1. Tailgate the vehicle closely to reduce wind resistance before pulling out
2. Honk continuously and flash high-beams to force them off the road
3. Keep well back to get a better view of the road ahead, signal, check mirrors, and ensure there is enough clear road to complete the pass
4. Overtake immediately and rely on air brakes if oncoming traffic appears
