When merging onto a high-speed highway in a small commercial bus, what is the correct procedure?

1. Stop at the end of the ramp and wait for a gap in highway traffic
2. Accelerate in the acceleration lane to match the speed of highway traffic, signal, check mirrors and blind spots, and merge smoothly into the gap
3. Force your way into the highway lane immediately, as highway traffic must yield to buses
4. Keep your speed low to force highway traffic to slow down for you
