The DVLA has confirmed that motorists suffering from high blood pressure could face a £1,000 fine for failing to disclose the condition. The agency stresses that hypertension, which puts strain on the circulatory system, increases the risk of sudden medical episodes such as fainting, dizziness, headaches, and impaired concentration while driving.
Drivers Must Stop Driving with Malignant Hypertension
According to the DVLA, drivers diagnosed with malignant hypertension—also known as accelerated hypertension—must stop driving immediately. They can only resume when a doctor confirms the condition is well controlled. The DVLA states: "You must stop driving if a doctor says you have malignant hypertension."
Penalties for Non-Disclosure
The DVLA warns: "You can be fined up to £1,000 if you do not tell DVLA about a medical condition that affects your driving. You may be prosecuted if you’re involved in an accident as a result." This applies to any condition that could impair driving ability, including high blood pressure.
Thresholds for Bus, Coach, and Lorry Drivers
For bus, coach, or lorry drivers, the DVLA notes they do not need to report blood pressure if it remains consistently below 180/100mmHg. However, they must stop driving if readings are regularly above this level or if diagnosed with malignant hypertension.
Impact of Driving on Blood Pressure
Driving itself can affect blood pressure. Long hours in traffic and stress—such as road rage—can cause temporary surges in blood pressure. Motorists who declare a medical condition to the DVLA must also inform their car insurance company; failure to do so may invalidate their policy, potentially leading to higher premiums or denial of coverage.
Advice for Affected Drivers
The DVLA advises anyone with high blood pressure to consult their doctor and follow official guidance. Drivers should stop driving if advised by a physician and only return to the road when their condition is under control. Non-disclosure not only risks a fine but also legal consequences if involved in an accident.
