Driving a heavy goods vehicle (HGV) is a significant responsibility that requires good physical health, clear vision and the ability to drive safely over long distances. To help keep professional drivers and other road users safe, the Driver and Vehicle Licensing Agency (DVLA) requires HGV drivers to meet specific Group 2 medical standards before they can apply for or renew their licence.
Whether you're applying for your first HGV licence, renewing your entitlement every five years after the age of 45, or completing your annual medical after turning 65, understanding the DVLA's medical requirements can help you avoid unnecessary delays to your application.
This guide explains everything you need to know about HGV medical requirements in the UK, including who needs an HGV medical, when your medical is due, what the D4 medical report is, what happens during the examination, common medical conditions that may affect your licence, blood pressure requirements, and how often you'll need to renew.
At Private Medical Clinic, our GMC-registered doctors provide fast, professional HGV (D4) medicals with same-day appointments available at clinics across the UK.
An HGV medical, also known as a D4 driver medical, is a mandatory health assessment required by the DVLA before you can apply for or renew an HGV or LGV licence.
The purpose of the medical is to ensure that professional drivers meet the DVLA Group 2 medical standards, which are designed to reduce the risk of medical conditions affecting road safety. During your appointment, the examining doctor completes the DVLA D4 Medical Examination Report, which is submitted as part of your licence application or renewal.
The medical assesses several aspects of your health, including:
At Private Medical Clinic, our experienced GMC-registered doctors complete your D4 medical report during your appointment, making the process quick and straightforward.
The DVLA D4 Medical Examination Report is the official medical form used when applying for or renewing a Group 2 driving licence, including HGV, LGV and many PCV licences.
The report is completed by the doctor carrying out your medical examination and records important information about your health, eyesight and medical history. It helps the DVLA determine whether you meet the required medical standards to drive professionally.
The D4 report typically includes:
In most cases, you'll submit your completed D4 report to the DVLA as part of your licence application or renewal. If additional medical information is required, the DVLA may contact your GP or Specialist Referrals before making a licensing decision.
You'll need an HGV medical if you're applying for or renewing certain Group 2 driving licences issued by the DVLA. These medical standards apply to drivers operating larger goods vehicles and passenger-carrying vehicles where higher medical standards are required.
You may need an HGV medical if you're applying for or renewing any of the following:
If you're applying for your first HGV licence, you'll need a completed D4 medical report before your provisional licence application can be processed. Existing licence holders must also complete medical assessments at the renewal intervals specified by the DVLA.
Knowing when your HGV medical is due is essential for keeping your licence valid and avoiding interruptions to your ability to work.
First HGV Licence Application
Anyone applying for their first HGV or LGV licence must complete an HGV medical before the DVLA will consider their application. Your doctor will complete the D4 Medical Examination Report, which is submitted alongside your application.
From Age 45 to 65
After your initial medical, you'll normally need to renew your HGV medical every five years from the age of 45 until you reach 65.
Age 65 and Over
Once you reach 65 years of age, the DVLA requires an annual HGV medical to maintain your Group 2 driving entitlement.
In some circumstances, the DVLA may issue a licence for a shorter period if further medical monitoring is required due to an underlying health condition.
If you're unsure when your HGV medical is due, you can:
Booking your medical a few weeks before your licence expires can help prevent delays to your renewal application.
One of the most common questions drivers ask is "How long does an HGV medical last?"
The medical examination itself doesn't have a separate expiry date. Instead, it supports your licence application or renewal, and the validity of your licence depends on your age, medical history and the DVLA's decision.
In general:
Some drivers may be asked to undergo medical assessments more frequently if they have certain medical conditions that require ongoing review.
To hold or renew an HGV licence in the UK, you must meet the DVLA Group 2 medical standards, which are stricter than those for ordinary car drivers (Group 1). These standards are designed to ensure professional drivers are medically fit to operate larger vehicles safely.
During your HGV medical, the examining doctor will assess whether any health conditions could affect your ability to drive safely. Having a medical condition does not automatically prevent you from holding an HGV licence. The DVLA considers each case individually, taking into account the condition, how well it is controlled and whether it meets the required medical standards.
Some of the main areas assessed include:
If you have an existing medical condition, the DVLA may request additional information from your GP or specialist before making a decision about your licence.
Many drivers ask, "What does an HGV medical involve?" Fortunately, the examination is straightforward and usually takes around 15 to 20 minutes.
Your doctor will complete the DVLA D4 Medical Examination Report while carrying out a series of routine health checks.
The appointment typically includes:
Medical History
You'll be asked about your medical history, including any previous or current health conditions that may affect your ability to drive safely.
Your doctor may ask about:
Being honest about your medical history is important, as failing to declare a relevant condition could affect your driving entitlement.
Eyesight Assessment
Good vision is essential for safe driving.
During your medical, your eyesight will be assessed to ensure it meets the DVLA Group 2 standards. If you wear glasses or contact lenses, remember to bring them with you to your appointment.
Your doctor will assess:
If you've recently had an optician's eye test, you may also be able to use this information to complete the eyesight section of the D4 form, depending on your circumstances.
Blood Pressure Check
Your blood pressure and pulse will be measured during the appointment.
This helps assess your cardiovascular health and determine whether your blood pressure is within an acceptable range for professional driving.
If your blood pressure is higher than expected, your doctor may repeat the reading after you've had time to relax. In some cases, further assessment or treatment by your GP may be recommended before your D4 report can be completed.
Many drivers with well-controlled high blood pressure continue to meet the DVLA's medical standards.
Physical Examination
The doctor will perform a basic physical examination to assess your general health and fitness to drive.
This may include checking:
The examination is not invasive and is designed to ensure you can safely operate a heavy goods vehicle.
Medications Review
Some prescription medications can affect alertness, concentration or reaction times.
Your doctor will review any Private Prescriptions medications you're currently taking and determine whether they may affect your ability to meet the DVLA's medical standards.
Bring an up-to-date list of your medications or repeat prescription if possible.
One of the most common concerns drivers have is whether their blood pressure could affect their HGV licence.
During every HGV medical, your blood pressure will be checked as part of the examination. If your reading is slightly elevated, your doctor may ask you to rest before repeating the measurement.
A raised blood pressure reading doesn't automatically mean you'll fail your medical. Many people with well-controlled hypertension continue to hold an HGV licence without any problems.
However, if your blood pressure remains consistently high, your doctor may advise further assessment or treatment before completing your D4 report.
Maintaining a healthy lifestyle, taking prescribed medication as directed and attending regular GP reviews can all help keep your blood pressure under control.
Certain medical conditions must be declared to the DVLA because they could affect your ability to drive safely. In many cases, drivers can continue driving once their condition is appropriately managed.
Examples include:
Diabetes
Drivers treated with insulin or certain diabetes testing medications may need to meet additional DVLA requirements. Many people with well-controlled diabetes continue to hold an HGV licence.
Heart Conditions
Some heart health conditions require further assessment before a licence can be issued or renewed. The DVLA may request additional information from your cardiologist or GP.
Epilepsy and Seizures
A history of seizures may affect your entitlement to hold an HGV licence. Eligibility depends on the nature of the condition and the current DVLA medical standards.
Sleep Apnoea
Obstructive sleep apnoea can cause excessive daytime sleepiness, increasing the risk of accidents. Effective treatment often enables drivers to continue driving safely.
Vision Problems
Drivers must meet minimum eyesight standards. If your vision changes, you should seek advice promptly.
Mental Health Conditions
Some mental health conditions may require review by the DVLA, particularly if they affect concentration, judgement or awareness.
If you develop a medical condition that could affect safe driving, you may have a legal duty to inform the DVLA.
Yes, it's possible to not meet the DVLA's medical standards during an HGV medical. However, many medical conditions can be successfully managed, and further treatment or assessment may allow you to retain or regain your driving entitlement.
Reasons why further assessment may be required include:
If there are concerns during your medical, your doctor will explain the next steps. In some cases, the DVLA may ask for additional reports from your GP or specialist before making a final licensing decision.
Preparing for your appointment can help ensure the process runs smoothly.

An HGV medical is a health assessment required by the DVLA to ensure drivers meet the Group 2 medical standards needed to drive heavy goods vehicles safely. The examination includes a review of your medical history, eyesight, blood pressure and general health.
The D4 Medical Examination Report is the official DVLA form completed during your HGV medical. It records the findings of your examination and forms part of your HGV licence application or renewal.
Your first HGV medical is required when applying for your licence. After that, you'll usually need one every five years from the age of 45 and every year after turning 65. You can also check your driving licence expiry date or contact the DVLA if you're unsure.
The medical itself doesn't have a separate expiry date. Instead, it supports your HGV licence application or renewal. Most drivers renew every five years after age 45 and annually after age 65, unless the DVLA issues a shorter licence period due to a medical condition.
How often do HGV drivers need a medical?
Most HGV drivers require a medical:
Some drivers may need more frequent medical reviews depending on their health.
The examination usually includes:
Appointments typically take around 15 to 20 minutes.
Your blood pressure is measured as part of the medical examination. If it's higher than expected, the doctor may repeat the reading after you've rested. Many drivers with well-managed high blood pressure continue to meet the DVLA medical standards.
Not necessarily. A single elevated reading doesn't automatically prevent you from obtaining or renewing your licence. If your blood pressure remains consistently high, you may need further assessment or treatment before your D4 report can be completed.
Yes, depending on the type of diabetes and your treatment. Many drivers with well-controlled diabetes continue to hold an HGV licence, although the DVLA may require additional medical information in some cases.
Yes. Untreated obstructive sleep apnoea can affect your ability to drive safely. However, many drivers continue to hold an HGV licence once their condition is appropriately treated and controlled.
Yes. Please bring:
Yes. Your GP may be able to complete your D4 medical report, although many drivers choose a private clinic for faster appointments, shorter waiting times and greater flexibility.
Yes. Private Medical Clinic has clinics in locations across the UK, making it easy to book an appointment close to home or work.
Once your examination is complete, your doctor will finalise your D4 Medical Examination Report. You'll then submit the paperwork to the DVLA, who will review your application and make a licensing decision.
In some circumstances, you may be able to continue driving while the DVLA processes your application. This depends on your individual circumstances and whether you meet the relevant legal requirements. If you're unsure, seek guidance from the DVLA before continuing to drive.
The cost of an HGV medical varies depending on the provider. Private clinics often offer fixed-price appointments that include completion of the D4 medical report. Contact your chosen clinic for current pricing.
A urine test isn't routinely required for every HGV medical. However, the examining doctor may request additional checks if clinically appropriate or where further assessment is needed.
If the DVLA requires additional medical evidence, they may contact your GP, consultant or another healthcare professional before making a final decision about your licence.
Yes. Once you reach the age of 65, you'll normally need to complete an HGV medical every year to maintain your Group 2 driving entitlement.
Yes. Many drivers book their HGV medical several weeks before their licence expires to allow enough time for the DVLA to process their renewal application and avoid interruptions to their ability to work.
