What does uncontrolled vertigo indicate regarding a driver’s qualification?

Uncontrolled vertigo is a condition that can significantly impair a person's balance, spatial orientation, and overall ability to operate a vehicle safely. The FMCSA guidelines prioritize safety and the ability of a driver to maintain control of their vehicle in all situations. Because uncontrolled vertigo can lead to sudden and severe episodes that might incapacitate a driver, it is classified as a disqualifying condition.

When vertigo is uncontrolled, it does not allow for reliable management or predictability, which is critical for driving. Since drivers must be able to react promptly to any potential hazards on the road, any condition that could lead to sudden incapacitation is viewed as a serious safety risk. Therefore, the FMCSA recognizes uncontrolled vertigo as a disqualifying condition, underscoring the importance of maintaining a safe driving environment for both the driver and the public.
