Drivers diagnosed with certain high blood pressure conditions may face penalties and driving restrictions under DVLA rules. While high blood pressure alone does not always require notification, a diagnosis of malignant hypertension—also known as accelerated hypertension—means you must stop driving immediately. Failure to comply could result in a fine of up to £1,000 and possible prosecution if involved in an accident.
According to the DVLA, standard high blood pressure does not need to be reported if it is your only medical condition and does not produce side effects affecting your ability to drive, such as severe dizziness. However, if your blood pressure leads to complications like stroke or heart conditions, or causes treatment side effects that impair driving, you must inform the DVLA.
For professional drivers operating buses, coaches, or lorries, the rules are more stringent. You must notify the DVLA if your blood pressure consistently exceeds 180/100 mmHg or if a doctor diagnoses malignant hypertension. If your blood pressure remains below this threshold, you may continue driving without reporting it.

To comply with DVLA procedures, drivers whose blood pressure is consistently above 180/100 mmHg (without malignant hypertension) need to complete form BP1V. Those diagnosed with malignant hypertension must submit form VOCH1.
You may resume driving once a medical professional confirms your condition is well controlled. The DVLA’s focus is on preventing sudden disabling events like strokes or hypertensive crises, which can jeopardize road safety.
