If your vehicle suffers a **breakdown** on a **motorway** and cannot maintain the appropriate speed, it is important **not to obstruct traffic**. In this case, you should **drive on the right shoulder** and **exit the motorway at the first exit** you find. This is crucial to ensure the safety of all road users and minimize the risk of accidents.

- **Driving on the shoulder**: If the vehicle can still move, but at a reduced speed, you should use the right shoulder to avoid interfering with normal traffic.
- **Exit at the first exit**: By leaving the motorway as soon as possible, you reduce the time the vehicle is in a potentially dangerous situation.

Remember that stopping on the shoulder or looking for a service area is not the correct option in this case, as it could continue to disrupt traffic. Additionally, requesting assistance from the shoulder is neither safe nor appropriate if the vehicle can still move.
