Allergic rhinitis may enable a driver to be certified if they are treated with:

In the context of certifying a driver with allergic rhinitis, the use of nasal steroid sprays and non-sedating antihistamines is recognized as an effective treatment that can help manage the symptoms without adversely impacting the individual's ability to drive safely. Allergic rhinitis can cause nasal congestion and sneezing, which may distract a driver; however, these symptoms can often be controlled with appropriate medications.

Nasal steroid sprays reduce inflammation in the nasal passages, leading to improved airflow and decreased congestion. Non-sedating antihistamines effectively alleviate the symptoms of allergic rhinitis, such as itching and sneezing, without causing drowsiness, which is critical for maintaining attention and focus while driving. When treated with these medications, individuals with allergic rhinitis can usually function well, thereby meeting the necessary medical standards required for certification.

In contrast, severe conjunctivitis that affects vision, uncontrollable sneezing fits, or sinusitis with severe headaches can significantly impair a driver's ability to operate a vehicle safely. These conditions either relate to visual impairment or generate symptoms that can distract or incapacitate an individual, making it critical to ensure that any medical condition is well-managed before granting certification.
