Overtaking should not be performed in case of doubt because it can be dangerous and is prohibited in certain situations. Here we explain why:

- **Limited visibility:** You should not overtake on curves, hilltops, or when there is fog, heavy rain, or sun glare, as these conditions reduce visibility and increase the risk of accidents.

- **Road conditions:** If you cannot clearly see the entire road or if there is a vehicle ahead that is also overtaking, it is better not to overtake. This avoids dangerous situations where you might encounter an oncoming vehicle.

- **Safety of other users:** Overtaking at pedestrian crossings, intersections with cyclist paths, or level crossings is prohibited, as you could endanger pedestrians and cyclists.


- **Space and time to maneuver:** Before overtaking, you must ensure that you can return to your lane without risk to other vehicles. If you are not sure you have enough space or time, it is better not to overtake.

In summary, if you have doubts about the safety of an overtaking maneuver, it is safer not to perform it. Safety should always be the priority when driving.
