If you lose your **driving license**, it is important to request a **duplicate** at the **Provincial or Local Traffic Headquarters**. This is necessary because the license is an official document that certifies your ability to drive legally.

- **Having a photocopy** of the license is not enough, as it does not have legal validity for driving.
- It is also not necessary to retake the **aptitude tests** or the **theoretical and practical exams** if you have only lost the document. These exams are only necessary in specific situations, such as when you lose all the points on your license due to serious infractions.

Therefore, the correct action is to request a duplicate to continue driving legally.
