What does a driver need to check before attempting to overtake?

When preparing to overtake, it is essential for a driver to assess the visibility of the road ahead. This factor is critical because the driver needs to ensure that there is a clear line of sight when attempting to pass another vehicle. If visibility is poor due to curves, hills, or other obstacles, the driver may not see oncoming traffic or other potential hazards, increasing the risk of an accident. Adequate visibility allows for safe judgment on whether it is appropriate to overtake, including the distance and speed of approaching vehicles.

While checking traffic lights, the speed of the vehicle in front, and considering passenger comfort are important aspects of driving, they do not directly pertain to the safety of overtaking. Traffic lights primarily indicate whether a driver should stop or go, while the speed of the vehicle in front is crucial for the timing of the maneuver but is not as critical as ensuring there is a clear view of the road ahead. Passenger comfort is related to the quality of the ride, which should not take precedence over safety considerations during an overtaking scenario.
