1: Get ready for a stop, therefore reduce your speed
2: You are getting close to a a downgrade, therefore all drivers should move close carefully. At this point, you apply your brake slowly. The road ahead has a sharp curve. Slow down, keep to your right, then don't overtake. You've almost reached the end of the lane.
3: Another road crosses the highway ahead. Watch left and right carefully for other traffic.
