A healthy 43-year-old female bus driver allergic to aspirin may be certified if:

In the context of medical certification for commercial drivers, particularly for someone who is a healthy 43-year-old female bus driver with an aspirin allergy, the primary consideration is her overall medical fitness to perform her duties safely. If the individual does not have any disqualifying medical conditions such as seizures or other significant health issues that could impair her ability to safely operate a vehicle, she can be certified for a certain period.

When a driver is healthy and doesn’t have disqualifying conditions, they may typically be granted a certification period of two years. This duration is standard for drivers who meet the medical criteria set forth by the DOT. The driver's allergy to aspirin does not directly affect her ability to operate a bus nor represent a threat to public safety, provided her allergy is managed and poses no risk of severe reactions that could impair her driving.

Other scenarios presented would require further evaluation or are based on the presence of disqualifying conditions:

• An individual with a history of seizures would need neurological clearance, which may lead to temporary certification or disqualification.

• The option proposing temporary certification for three months suggests that there is a need for further medical evaluation, which is unnecessary in this case, given her stated health and lack of history of seizures.

• Certification annually
