On a motorway, it is important to **adapt the speed to the circumstances** of the traffic and road conditions, without exceeding **120 km/h**. This limit is set to ensure the safety of all road users.

- **Speed limits**: On motorways, the maximum permitted speed is 120 km/h. This is because, at higher speeds, accidents can be more severe and the chances of survival decrease.
- **Road conditions**: Speed must be adjusted according to the type of road and its conditions. For example, if there is heavy traffic or the road is in poor condition, it is necessary to reduce speed to maintain safety.
- **Safety**: Speed limits are designed so that all vehicles can travel safely and comfortably. Driving at an appropriate speed reduces the risk of accidents and their consequences.

Therefore, the speed must be adapted to the circumstances, always respecting the maximum limit of 120 km/h on motorways.
