In case of an **emergency** on a motorway, such as an accident or a breakdown, you may need to stop your vehicle. If the vehicle cannot continue moving, you must park it where it **least obstructs** other drivers. This may include the **right shoulder**, the **left shoulder**, or even the **central reservation** if there is no other alternative.

- **Motorway emergencies**: If the vehicle cannot continue, stopping in the central reservation is allowed when no other option is available. This is to minimize risk and avoid obstructing traffic.

- **Safety measures**: When stopping, it is crucial to turn on the **hazard lights** and, if possible, place the **warning triangles** to alert other drivers. Additionally, occupants should wear **reflective vests** and exit the vehicle if it is safe to do so.

In summary, stopping in the central reservation is a valid option in emergency situations when there is no other alternative, always prioritizing safety and proper signaling.
