LGV Medical Explained: What It Is, What It Costs, and Why It's the Same as an HGV Medical

If your employer, training provider, or the DVLA has told you that you need an "LGV medical," you might be wondering what exactly that involves, how much it costs, and where to get one. You may also have noticed people talking about "HGV medicals" and wondered whether that is something different entirely.

The short answer: it is not. But let us walk through everything properly so you know exactly what to expect.

What is an LGV medical?

An LGV medical is a health examination required by the DVLA for anyone who wants to drive a large goods vehicle. "LGV" stands for Large Goods Vehicle, and the medical ensures you meet the higher physical standards needed to drive vehicles over 3,500 kg safely on public roads.

The examination uses the DVLA's D4 medical form, which must be completed and signed by a registered doctor. You will need this medical when you first apply for your provisional LGV licence, and then at renewal intervals throughout your driving career (every five years from age 45, then annually from age 65).

This is a legal requirement, not optional. Without a valid D4 medical, the DVLA will not issue or renew your LGV licence.

LGV vs HGV -- is there a difference?

This is one of the most common questions we hear, and the answer is refreshingly simple: there is no difference between an LGV medical and an HGV medical. They are the same examination, using the same D4 form, assessing the same health standards.

The confusion comes from a change in terminology. "HGV" (Heavy Goods Vehicle) was the term used in UK law until 1992, when European legislation replaced it with "LGV" (Large Goods Vehicle). In everyday language, though, most drivers, employers, and even some training companies still say "HGV." Both terms refer to the same category of vehicle and the same driving licence.

So whether you have been asked to book an LGV medical or an HGV medical, you need exactly the same appointment. One form, one examination, one result.

What does the examination involve?

The LGV medical examination is thorough but straightforward. A registered doctor will work through the DVLA's D4 form with you, covering several key areas of your health:

• Vision - You will need to read a number plate at the required distance, and the doctor will check your visual acuity and visual fields.
• Blood pressure - A standard reading to check your cardiovascular health.
• Urine test - A dipstick test screening for sugar and protein, which can indicate conditions like diabetes or kidney problems.
• Medical history review - The doctor will ask about any current or past medical conditions, medications, surgeries, and family history relevant to driving fitness.
• Physical examination - A general assessment of your neurological and musculoskeletal health, including reflexes, coordination, and mobility.
• BMI check - Your height and weight will be recorded.

The whole process typically takes around 10 minutes with an experienced doctor. Our patients regularly tell us the appointment feels unhurried despite being efficient; as one recent review put it, "thorough, not a tick-box exercise."

How much does an LGV medical cost?

LGV medical costs can vary significantly depending on where you go. Many GP surgeries offer D4 medicals, but because it is classed as private (non-NHS) work, prices at GP practices tend to be higher and appointment availability can be limited.

At South Wales Driver Medicals, we keep our pricing fair and transparent:

You will see the doctor on time, have a thorough examination, and leave with your completed D4 form, ready to send to the DVLA. No hidden fees, no follow-up charges.

FAQs

Do I need an LGV medical to drive a lorry?

Yes. If you want to hold a Category C or C+E licence (which covers vehicles over 3,500 kg), the DVLA requires a D4 medical examination before they will issue or renew your licence.

Is an LGV medical the same as a D4 medical?

Yes. The D4 medical form is the document used for all Group 2 driving licence applications, which includes both LGV and PCV (bus and coach) drivers. When people say "LGV medical," "HGV medical," or "D4 medical," they are all referring to the same examination.

Can I use my own GP for an LGV medical?

You can, but many drivers find that GP surgeries charge more and have longer waiting times for what is considered private work. A dedicated driver medical clinic often provides a quicker, more affordable option.

How often do I need to renew my LGV medical?

Up to age 45, your LGV licence lasts until you turn 45 (or for five years, whichever is longer). From 45, you will need a new medical every five years. From 65, it becomes an annual requirement.

What if I have a medical condition? Will I fail?

Having a medical condition does not automatically mean you will fail. Many drivers with well-managed conditions like diabetes, high blood pressure, or sleep apnoea continue to hold their licences. The doctor assesses whether your condition is controlled to the DVLA's standards. If you have concerns, speak to your GP before your appointment.

What should I bring to my appointment?

Bring your completed D4 form (filled in with your personal details), a form of photo ID, a list of any medications you take, and your glasses or contact lenses if you wear them for driving.
