What is a dangerous situation you may encounter when passing?

A dangerous situation when passing can occur if a vehicle unexpectedly approaches from the opposite direction, especially on a narrow road. Additionally, if the driver being passed accelerates or changes lanes suddenly, it can lead to a collision. Poor visibility due to curves, hills, or weather conditions can also increase the risk during a passing maneuver. It's crucial to ensure the road is clear and that there is enough space to complete the pass safely.
