Overtaking several vehicles at once is possible, but only under certain conditions. It is essential to have **sufficient assurance** that you can return to the right lane without causing inconvenience or danger to the vehicles you have overtaken. This means you must ensure there is **enough space** to return to the lane safely and without interfering with traffic.

- **Visibility and road conditions:** You should not overtake in situations where visibility is limited, such as on sharp curves, hill crests, or adverse weather conditions (fog, heavy rain, sun glare). These situations can prevent you from clearly seeing oncoming traffic, increasing the risk of an accident.

- **Space and speed:** When overtaking, it is crucial to maintain a **safe distance** from the vehicles you are overtaking and not exceed the permitted speed limit. If at any point you cannot maintain this distance or if an oncoming vehicle approaches, you must be prepared to reduce speed and safely return to your original lane.

- **Proper signaling:** Once you have overtaken, it is important to use the signaling lights to indicate your intention to return to the right lane. This helps inform other drivers of your movements and avoids surprises that could cause accidents.

In summary, overtaking several vehicles is allowed only if you can do so safely, with good visibility and enough space to return to the right lane without endangering other drivers.
