If you have **respiratory allergies**, it is important to take certain precautions when driving to prevent symptoms from interfering with your ability to drive safely. One of the key recommendations is to **keep the vehicle windows closed**. This helps prevent allergens such as pollen from entering, which can trigger allergic symptoms like sneezing, itchy eyes, or nasal congestion.

Additionally, it is suggested to use the air conditioning gently and ensure that the vehicle and ventilation ducts are clean. These measures help maintain a controlled environment inside the car, reducing exposure to allergens and improving comfort and safety while driving.
