HGV and taxi driver medicals
What HGV (D4) and taxi driver medicals involve, the standards applied, and how to book one quickly.
Key points
-
An HGV medical completes the DVLA D4 form: vision testing, blood pressure, heart and neurological history, diabetes review and screening questions for sleep apnoea; taxi medicals follow similar local-authority standards.
-
Bring photographic ID, your glasses or contact lenses and prescription, a list of medications, and any specialist letters about existing conditions.
-
The examination takes 20 to 30 minutes and the signed form is usually issued on the spot.
-
A registered doctor completes and signs the form; the DVLA or licensing authority makes the final licensing decision, not the examining doctor.
About this test
Published 2026-09-27 · Next review 2027-09-27
Driver medicals are standards-based rather than exploratory: the doctor certifies whether you meet published DVLA Group 2 vision, cardiovascular, neurological and diabetes standards. Common tripping points are uncorrected vision, blood pressure above the threshold on the day (a home readings diary helps), and insulin-treated diabetes, which carries specific monitoring requirements rather than an automatic bar.
Dedicated driver medical clinics and many private GPs offer same-week appointments at fixed fees, typically far below a standard private consultation. Waiting lists for NHS outpatient assessment remain long in much of the UK, and many of these checks are not offered on the NHS at all unless you meet strict criteria. Private clinics can usually see you within days on a self-pay basis, with no GP referral needed in most cases.
Frequently asked
Common questions about HGV and taxi driver medicals.
Quick, plain-English answers to what people ask us most.
-
What is an HGV and taxi driver medical?
This is a medical examination required to confirm that a driver meets the health standards needed to hold an HGV, PCV, or taxi and private hire licence. It follows specific DVLA or licensing authority guidelines and is usually carried out by a doctor trained in this type of assessment.
-
Why would I need this medical?
It's a legal requirement for obtaining or renewing an HGV, bus, taxi or private hire licence, and is typically needed periodically, such as every one to five years depending on age and licence type, or if a relevant health condition arises. Local licensing authorities and the DVLA set out exactly when it's required.
-
Do I need to prepare for this medical?
Bring a list of your current medications, details of any medical conditions, and your glasses or contact lenses if you wear them, since vision will be tested. Some clinics ask you to complete a health questionnaire before your appointment.
-
What happens during the medical?
The doctor will check your vision, blood pressure, heart and lungs, urine, and review your medical history and any relevant conditions against the required standards. The examination typically takes around 30 minutes.
-
Does it hurt or carry any risks?
The examination is non-invasive and doesn't hurt; it may include a urine sample and a blood pressure check, both low risk. There's no discomfort beyond standard examination steps.
-
How long do results take?
In most cases, the doctor completes the relevant certificate at the appointment itself. Occasionally, if further tests or specialist input are needed, this can take a little longer before the certificate is finalised.
-
What if a health issue is identified during the medical?
If a condition needs further assessment, such as blood pressure or vision concerns, the doctor may ask you to have this addressed before signing off, or refer you for a specialist opinion. This is to ensure driving standards are met safely, and the doctor will explain exactly what's needed.
-
How much does this medical cost privately, and is it available on the NHS?
These medicals are not typically provided free on the NHS, as they're a requirement for licensing rather than routine medical care, and are usually paid for privately regardless of provider. Cost varies by provider, and private occupational health clinics can often offer quick appointments.
-
Is the medical assessment reliable for licensing purposes?
Yes, it follows standardised DVLA and licensing authority medical criteria, so a properly completed assessment is recognised and accepted by licensing bodies. Using a doctor experienced in these specific medicals helps ensure the paperwork is completed correctly first time.
-
How do I book an HGV or taxi medical privately, and how quickly can I be seen?
You can book directly with a private clinic offering these medicals, often with same-week appointments available.
