When considering overtaking a tractor, what should you do if you are unsure about safety?

Determining whether to overtake a vehicle, especially one as large and potentially slower-moving as a tractor, requires careful consideration of safety. Choosing not to overtake if you are in doubt is the best decision because it prioritizes safety over haste or the desire to continue driving at speed.

Overtaking a vehicle involves not just assessing the vehicle you wish to pass, but also the conditions of the road, the behavior of other vehicles, and any potential hazards that may arise. If there is any uncertainty about whether the maneuver can be completed safely, then the safest course of action is to refrain from overtaking. This reduces the risk of accidents that could arise from making an ill-timed decision.

The other options might suggest taking unnecessary risks or relying on judgment that could lead to dangerous situations. Using the horn, making a decision closer to the vehicle, or only considering oncoming traffic does not adequately address the overall context of road safety, particularly when dealing with larger vehicles that may have limited visibility and maneuverability. Prioritizing caution and making the decision to hold back until you can assess the situation fully is the responsible approach for ensuring safety on the road.
