The HGV medical test, conducted by qualified doctors, is designed to ensure that drivers are medically fit to operate a Heavy Goods Vehicle safely. While road safety is essential for all drivers, the size and weight of HGVs make it particularly important that drivers meet strict medical standards to protect both themselves and other road users.
Drivers of Group 2 vehicles—including lorries, buses, and minibuses—are held to higher medical standards than those driving Group 1 vehicles, such as cars and motorcycles. This is the reason why the HGV medical test exists.
Before being issued a first HGV licence, all drivers must successfully complete an HGV medical assessment. Let’s take a closer look at what this test involves and what drivers can expect.
An HGV medical is a mandatory test for anyone seeking to obtain or maintain an HGV drivers’ licence. You cannot be issued an HGV licence without first passing this assessment.
Appointments typically take 30–45 minutes and are arranged in advance, with fees set by GP practices.
For full details on HGV medical tests and when form D4 should be completed, refer to the official GOV.UK guidance.
HGV medical assessments should be conducted at a doctor’s surgery or during an appointment with a qualified doctor present. Any General Medical Council (GMC) registered NHS GP, as well as most private doctors licensed to practice in the UK or registered within the EU, can carry out the test.
The examination must be pre-booked, and although it is a routine assessment, it typically takes 30–45 minutes to complete.
The HGV medical includes a vision test, which may need to be performed by an optician or optometrist. When booking your appointment, your doctor will confirm whether they can carry out the visual component or if a separate referral is required.
The HGV medical assessment is a routine examination required for anyone applying for or renewing an HGV licence. During the appointment, your doctor will complete the DVLA form D4, which records the results of your assessment. If you are generally healthy and have been honest in previous assessments, there is usually nothing to worry about.
The assessment begins with a conversation about your overall health and medical history. This is your opportunity to mention any conditions or concerns that could affect your ability to drive safely. Your doctor will ask about previous medical conditions, ongoing treatments, and any other relevant health information.
A key component of the HGV medical is a vision test. This may be conducted by your doctor or, in some cases, referred to an optician or optometrist. All HGV drivers must be able to read a number plate from 20 metres, with or without corrective lenses. Vision standards include:
The test ensures that your eyesight is sufficient to operate a large vehicle safely on the road.
The final section of the HGV medical covers multiple health categories that could impact driving safety:
Other medical conditions that impair a driver’s ability to operate an HGV safely may also be reviewed. The overall aim is to ensure road safety for all by confirming that drivers are fit to operate large vehicles responsibly.
The cost of an HGV medical test is not set by the DVLA. Instead, fees are determined by individual doctor’s surgeries. While some surgeries may not charge, most do apply a fee to cover the extended appointment time required for the assessment.
Many drivers choose to pay privately, as NHS appointments often have long waiting times and may still involve a charge. Private providers can sometimes offer quicker assessments and faster completion of the required DVLA form D4.
Typically, the driver is responsible for covering the cost of the HGV medical. In some cases, employers may offer to cover part or all of the fee, which should be discussed directly with your employer.
The duration of an HGV medical depends on your age at the time of assessment:
For those who have just passed their HGV medical but do not yet hold a licence, you have four months to take and pass your HGV driving test. If the test is not passed within this period, you will need to complete a new HGV medical before proceeding.
When attending your HGV medical, you should bring the following items:
It is the driver’s responsibility to report any changes to their medical condition that could affect their ability to drive safely. Failing to inform the DVLA of a relevant medical condition could result in fines or legal action if an accident occurs.
Additionally, all HGV licence holders are legally required to comply with the conditions of their licence, including any periodic medical reviews specified by the DVLA.
To stay on track, keep a note of when your next medical is due. The DVLA typically sends a reminder letter along with a D4 form every five years before your HGV medical expires. If you do not receive a reminder, it is your responsibility to follow up and ensure your medical is booked on time.
