HGV Medical Requirements

HGV Medical RequirementsThe HGV medical requirements can be broken down into four separate categories; Eyesight standards, Medical examination and form D4, If you have a change in health and Medical Standards to obtain and maintain a HGV license.

HGV Medical Eyesight Requirements

Drivers of all types of vehicles that drive in the EU MUST be able to read a number plate from a distance of 20.5 metres (67 feet) in good daylight. If you require glasses or contact lenses to see a number plate from this distance, then you MUST wear your glasses and contact lenses at all times when driving a HGV.

HGV Medical eyesight requirements also have an additional caveat, in that any applicant for a HGV license must have a visual acuity of at least

  • 6/9 in the better eye
  • 6/12 in the other eye


When wearing glasses or contact lenses, if needed. Both eyes must provide normal vision, which is defined at 120 degrees of vision and no evidence for diplopia (double vision). Applicants will also have to provide satisfactory uncorrected visual activity.

All applicants for a HGV license will need to have an uncorrected visual acuity of at least 3/60 in each eye. This is the normal binocular field of vision and your doctor will be able to use the standard Snellen test card to test your eyesight. If you only have eyesight in a single eye, you will need to declare this on an HGV medical application. Any HGV license holder that held a license prior to 1 January 1997 and whose eyesight doesn’t meet the HGV Medical eyesight standards will need to contact:

Medical Examination and Form D4

If this is your first application for a HGV license, you will need to obtain a medical report from your GP. You will also need to send off a medical report with any HGV license renewal for anyone aged over 45, unless you have already sent in a form in the past 12 months.

A medical examination will be needed in order to complete the D4 form (form DLM1 in Northern Ireland).

You will fill in the form while being examined by a doctor; they will fill in the other required sections. The report covers the following:

  • GP details
  • Vision
  • General health
  • Cardiac health
  • Psychiatric illness
  • Diabetes mellitus
  • Nervous system

It would be prudent to study the first two pages from the form, remove them before sending them off and keep them for future reference.

The NHS does not supply this medical report free, so your GP is entitled to charge you for the report. You will be responsible for the cost of the report, the DVLA cannot be chargeable and if your application to have a HGV license is declined the fee will not be refundable.

The medical form has to be with the DVLA within four months of the date when the GP signed the document.

Change in Health

It is the drivers responsibility to inform the Drivers Medical Group at DVLA, Swansea (DVA in Northern Ireland), if you have, or are developing a serious illness that is likely to persist for longer than three months and which will affect your driving.

HGV Medical Requirements and the Standards

If you have any of the following illnesses, you may be refused a HGV license:

  • Liability to seizure/epilepsy
  • Severe head injury, with serious continuing after-effects, or major brain surgery
  • Mental disorders
  • Eyesight defects
  • Any disorder causing vertigo within the past five years
  • Unconscious lapses within the last five years

  • Alcohol/drug issues
  • Serious difficulty communication by telephone, for instance to call in an emergency
  • Parkinson’s disease, multiple sclerosis or other chronic nervous disorders likely to affect the use of the limbs
