Which symptom is considered a complication of allergic rhinitis that may impair a driver's function?

Uncontrollable sneezing fits represent a significant complication of allergic rhinitis that can severely impair a driver’s ability to operate a vehicle safely. In the context of driving, such episodes can lead to sudden distractions, reduced attention to the road, and risks associated with impaired reaction times. When sneezing occurs unexpectedly and in rapid succession, it can cause a driver to momentarily lose control of the vehicle, increasing the potential for an accident.

Mild sneezing, seasonal allergies, and occasional nasal congestion typically do not pose the same level of risk. While these symptoms may be uncomfortable, they do not generally disrupt driving function to the extent that uncontrollable sneezing fits do, making the latter the most critical concern in terms of driving safety.
