Respiratory **allergy** can affect the driver's condition and presents symptoms such as **continuous sneezing** and **irritated eyes**. These symptoms are common in people who suffer from allergies, especially when exposed to allergens like pollen or dust. To mitigate these effects while driving, it is recommended to keep the windows closed, use the air conditioning gently, and wear sunglasses, as the sun can trigger sneezing. Additionally, it is important not to mix alcohol with medications and to avoid driving at dawn or in humid areas, where symptoms may intensify.

Therefore, **continuous sneezing and irritated eyes** are clear symptoms of allergy, making the first option the correct one.
