HGV Medical Guide

An HGV medical records whether an applicant meets the Group 2 medical standards for a lorry licence. The appointment covers the required history and checks, while the licensing authority makes the final decision on entitlement.

What Is an HGV Medical?

An HGV medical is a health assessment completed by a GMC-registered doctor to confirm that you meet the Group 2 medical standards required for professional drivers. During the appointment, the doctor completes the medical report named in your application. For a Northern Ireland licence issued by DVA, this is normally the DLM1 medical report. Drivers with a Great Britain licence issued by DVLA normally use the D4 medical report. The assessment helps ensure that drivers are medically fit to operate large commercial vehicles safely, protecting both the driver and other road users.

Who Needs an HGV Medical?

You will normally require an HGV medical if you are:
  • Applying for your first HGV (Category C or C+E) licence
  • Renewing your vocational entitlement at age 45
  • Renewing every five years between ages 45 and 65
  • Renewing annually from age 65 onwards
  • Requested by the DVLA or DVA following a medical condition or licence review
Medical requirements can vary depending on your circumstances, so it’s always worth checking your renewal paperwork if you’re unsure.

What Happens During an HGV Medical?

Most HGV medicals take around 15 minutes and involve a straightforward health assessment. Your appointment will usually include:
  • Review of your medical history
  • Blood pressure measurement
  • Vision assessment
  • Height and weight measurements
  • Urinalysis where required
  • General physical examination
  • Completion of the relevant DLM1 or D4 medical report
The assessment is designed to ensure you meet the Group 2 medical standards rather than to identify every possible health condition.

What Should You Bring?

To help your appointment run smoothly, remember to bring:
  • Your DLM1 or D4 medical form, as specified by your licensing authority
  • Valid photographic identification
  • Your driving glasses or contact lenses
  • Your latest glasses prescription if required
  • A list of current medications
  • Any relevant hospital or specialist correspondence
Having the correct paperwork available helps avoid unnecessary delays with your licence application.

Common Medical Conditions

Having a medical condition does not automatically prevent you from holding an HGV licence. Many drivers continue driving safely with well-managed health conditions. The doctor may ask about:
  • High blood pressure
  • Diabetes
  • Heart disease
  • Sleep apnoea
  • Neurological conditions
  • Mental health conditions
  • Vision problems
  • Current medication
If additional medical information is required, further reports may be requested before your licence application is processed.

How Often Do You Need an HGV Medical?

Medical frequency depends on your age and licensing circumstances.
  • First application for an HGV licence
  • At age 45
  • Every five years between 45 and 65
  • Annually after your 65th birthday
Certain medical conditions may require more frequent assessments depending on DVLA or DVA guidance.

How Can You Prepare?

Most drivers pass their medical without difficulty. A few simple steps before your appointment can help everything go smoothly.
  • Wear your usual driving glasses if required
  • Bring all requested paperwork
  • Know your current medications
  • Arrive well hydrated
  • Avoid rushing to your appointment, as stress may temporarily increase blood pressure

What Happens If Further Information Is Needed?

Occasionally, the examining doctor may require additional information before completing your medical. This could include reports from your GP or hospital consultant if you have a significant medical history. Providing accurate medical information during your appointment helps minimise delays.
