Should I inform the DVLA after a DVT or PE?
In the UK, whether you need to inform the Driver and Vehicle Licensing Agency (DVLA) after a Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE) depends largely on the type of driving licence you hold and whether the condition causes specific complications. For standard car or motorcycle drivers (Group 1), a simple DVT or PE generally does not need to be reported to the DVLA, provided there are no underlying complications. However, for professional drivers (Group 2, such as HGV or bus drivers), the rules are significantly stricter and often require formal notification and a temporary cessation of driving.

DVLA Notification Requirements Data
The following table outlines the standard reporting requirements for venous thromboembolism (VTE) based on current DVLA medical fitness to drive standards.
| Licence Type | Condition | Notification Required? | Mandatory Driving Gap? |
| Group 1 (Car/Bike) | Simple DVT or PE | No | None (if no complications) |
| Group 1 | If causing dizziness/syncope | Yes | Until symptoms resolve |
| Group 2 (HGV/Bus) | DVT or PE | Yes | Usually 3 months |
| Group 2 | On long-term anticoagulants | Yes | Requires specialist review |
Group 1 Drivers: Cars and Motorcycles
For most drivers in the UK, a DVT or PE is considered a ‘non-notifiable’ event. This means you do not need to contact the DVLA or surrender your licence. However, there is a legal requirement that you must not drive if your condition causes symptoms that could impair your safety, such as extreme pain, severe breathlessness, or dizziness.
If your PE was particularly severe and resulted in episodes of fainting (syncope) or significant heart strain, you must stop driving until your consultant confirms the risk of recurrence is managed. While you don’t necessarily inform the DVLA of the clot itself, you must inform them if you have any ‘chronic neurological’ or ‘cardiovascular’ conditions that arise as a result of the event.
Group 2 Drivers: HGVs and Buses
The rules for professional drivers are much more rigorous because of the size of the vehicles and the potential consequences of sudden incapacity. If you hold a Group 2 licence, you must inform the DVLA if you develop a DVT or PE.
Clinical data suggests that the risk of a recurrent, massive PE which could lead to sudden loss of consciousness is highest in the first three months. Consequently, Group 2 drivers are typically required to stop driving for a minimum of three months. Before returning to work, they often need a medical assessment to ensure the clot is stable and that they have not developed Chronic Thromboembolic Pulmonary Hypertension (CTEPH), which could cause sudden breathlessness or fainting behind the wheel.
Driving on Blood Thinners (Anticoagulants)
Being on blood thinners like Apixaban, Rivaroxaban, or Warfarin does not, on its own, prevent you from driving. However, you must be aware of the increased risk of internal bleeding if you are involved in an accident.
- Group 1: No need to notify the DVLA about being on anticoagulants for DVT or PE.
- Group 2: You must notify the DVLA. Your fitness to drive will be assessed based on the underlying reason for the medication and your risk of a ‘disabling’ bleed.
If you are on Warfarin, your Group 2 licence may be at risk if your INR levels are unstable, as this increases the chance of a spontaneous bleed that could lead to incapacity.
Triggers that necessitate stopping driving
Regardless of your licence type, certain ‘triggers’ in your recovery mean you must stop driving immediately and seek medical advice before returning to the road:
- Breathlessness at Rest: If a PE has left you struggling for air while sitting.
- Severe Leg Pain: If a DVT makes it painful or difficult to perform an emergency stop.
- New Dizziness: A potential sign of heart strain (Right Heart Failure) or medication side effects.
- Bleeding Episodes: If your blood thinners are causing significant nosebleeds or bruising.
Differentiation: Physical inability vs. Legal restriction
It is important to differentiate between being ‘legally’ allowed to drive and being ‘physically’ fit to drive. Even if the DVLA does not require notification, your insurance policy usually requires you to follow your doctor’s advice. If your doctor tells you not to drive for two weeks while your leg swelling goes down, and you have an accident during that time, your insurance may be void.
| Feature | Legal Restriction (DVLA) | Physical Fitness (Clinical) |
| Applicability | Based on licence class and safety | Based on personal symptoms |
| Notification | Specific to Group 2 or complications | Usually managed by your GP/Consultant |
| Main Concern | Sudden incapacity (fainting) | Ability to control the vehicle (braking) |
| Consequence | Licence revocation | Insurance invalidation / Safety risk |
Conclusion
For most car drivers in the UK, a DVT or PE does not require a formal report to the DVLA. However, for those who drive for a living, the notification is mandatory and usually involves a period away from the road to ensure long-term safety. In all cases, the primary responsibility lies with the driver to ensure they are physically capable of controlling the vehicle. Always consult your vascular or haematology specialist before returning to the driver’s seat to ensure you are meeting both medical and legal standards.
If you experience severe, sudden, or worsening symptoms, such as sharp chest pain, sudden shortness of breath while driving, or a leg that becomes too painful to operate the pedals, pull over safely and call 999 immediately.
‘Do I need to tell my car insurance company?’
Yes. Most insurance policies require you to disclose any change in your health that might affect your driving, even if the DVLA doesn’t need to know.
‘What happens if I don’t tell the DVLA (Group 2)?’
Failure to notify the DVLA of a reportable condition is a criminal offence and can result in a fine of up to £1,000 and prosecution if you are involved in an accident.
‘Can I drive after a DVT if my leg still aches?’
You must be able to perform an emergency stop safely and without hesitation. If the ache is distracting or limits your movement, you are not fit to drive.
‘How do I notify the DVLA?’
You can use the ‘V1’ form for Group 1 or the ‘VO1’ form for Group 2, available on the GOV.UK website.
‘How long after a PE can I drive a car?’
Most doctors suggest waiting at least 1 to 2 weeks until the initial pain and breathlessness have stabilized and you feel confident in your physical reactions.
‘Will I lose my HGV licence forever?’
Usually, no. Once you have completed the initial 3 months of treatment and a medical review confirms you are stable, your licence is typically restored.
‘What if I have a DVT in my right (driving) leg?’
This is particularly important as the right leg operates the accelerator and brake. You must wait until you have full, pain-free control of your foot and ankle.
