How can you tell if it's safe to pass another vehicle?

Determining whether it is safe to pass another vehicle relies heavily on visibility and road conditions. When the road is clear and you have good visibility, it allows you to assess not only the speed and position of the vehicle you're passing but also any potential hazards such as oncoming traffic, pedestrians, or obstacles in the road.

Good visibility means you can clearly see ahead and around the vehicle you intend to overtake, ensuring that you can safely return to your lane after passing. This consideration is crucial for maintaining safety for yourself, the vehicle being passed, and any other road users.

Other options, while they may seem relevant, do not cover the comprehensive assessment needed for safe passing. For example, just because a vehicle is going slightly slower does not guarantee safety if the road ahead is not clearly visible. Similarly, the absence of visible signs against passing does not mean passing is safe if visibility conditions are poor. Lastly, the speed of the other vehicle is a factor, but low speed alone doesn’t guarantee that the road conditions are suitable for passing. Each of these factors requires careful consideration within the context of the overall road situation.
