What condition leads to immediate disqualification from driving?

Unstable angina is a condition that presents a significant risk for sudden cardiac events, making it a serious concern for anyone operating a vehicle. This type of angina is characterized by unpredictable episodes of chest pain or discomfort that can occur at rest or with very little exertion, indicating that there is a higher risk of a heart attack. Due to its potential severity and the unpredictable nature of symptoms, individuals with unstable angina are deemed unfit for driving, as they may experience acute symptoms that could impair their ability to control a vehicle or react appropriately in driving situations.

In contrast, stable angina tends to have a predictable pattern triggered by exertion and usually resolves with rest or the use of nitroglycerin, thus posing less immediate risk while driving. Chest pain, while concerning, does not specifically confine itself to unstable angina and may have various causes that do not lead to immediate disqualification. Mild hypertension, while a health concern that should be monitored, does not typically interfere with one’s ability to drive safely unless it escalates to more severe conditions.
