What is the minimum asymptomatic period for vertigo and dizziness before certifying?

The minimum asymptomatic period for vertigo and dizziness before certifying a driver is two months. This requirement is in place because conditions causing these symptoms can significantly impair an individual’s ability to operate a commercial vehicle safely.

By having a two-month window where the individual does not experience any symptoms, medical examiners can ensure that the driver has a stable condition and is less likely to be affected by sudden episodes of dizziness or vertigo while driving. It is crucial for commercial driver safety that any underlying causes of these symptoms are fully evaluated and declared inactive before certification can occur.

A shorter asymptomatic period may not provide enough assurance that the driver has fully recovered and is capable of operating a vehicle without risking an incident. Hence, the two-month guideline serves as a precautionary measure to prioritize the safety of the driver and the public.
