What is a DLM1 Medical?

DLM1 Medicals in Northern Ireland: Form, Checks and Renewals

The DLM1 medical report is used by the DVA for Northern Ireland lorry and bus licence applications. A doctor completes the relevant sections after reviewing the Group 2 standards and the applicant’s medical history.

How the DLM1 Medical Report Is Used

The DLM1 is the medical examination report used by the Driver & Vehicle Agency (DVA) in Northern Ireland for vocational drivers. It confirms that you meet the medical standards required to hold a Group 2 driving licence for buses, coaches and lorries. Unlike drivers in England, Scotland and Wales, who use the D4 medical report, Northern Ireland drivers use the DLM1 form when applying for or renewing vocational driving entitlement. The medical must be completed by a doctor and submitted to the DVA as part of your application.

Who Needs a DLM1 Medical?

You may require a DLM1 medical if you are:
  • Applying for your first HGV or LGV licence
  • Applying for your first PCV (bus or coach) licence
  • Renewing your vocational driving entitlement
  • Returning to professional driving after a medical condition
  • Requested by the DVA to undergo a medical assessment
If your vocational licence was issued by the Driver & Vehicle Agency in Northern Ireland, the DLM1 form is generally the medical report you will need.

What Happens During a DLM1 Medical?

Your appointment is straightforward and usually takes around 15 minutes. During your medical, your doctor will complete the DLM1 report while carrying out a health assessment that typically includes:
  • Review of your medical history
  • Blood pressure measurement
  • Vision assessment
  • Height and weight measurements
  • Urinalysis where required
  • General physical examination
  • Completion of the DLM1 medical form
Our doctors will ensure every relevant section of the form is completed before you leave your appointment.

What Should You Bring?

To help your appointment run smoothly, please bring:
  • Your DLM1 medical form (if already downloaded)
  • Valid photo identification
  • Your driving glasses or contact lenses
  • A list of any regular medications
  • Relevant hospital or consultant letters if applicable
If you’re unsure which documents are required, our team will be happy to advise before your appointment.

Common Medical Conditions Considered

The purpose of the medical is to ensure you meet the Group 2 medical standards. The doctor may discuss any medical conditions that could affect your ability to drive safely.
  • Diabetes
  • High blood pressure
  • Heart conditions
  • Neurological disorders
  • Sleep apnoea
  • Mental health conditions
  • Vision problems
  • Current medication
Having a medical condition does not necessarily prevent you from holding a vocational licence. Many drivers continue to meet the required standards with appropriate treatment and management.

How Often Is a DLM1 Medical Required?

Most vocational drivers will require a medical:
  • When first applying for a vocational licence
  • At 45 years of age
  • Every five years between ages 45 and 65
  • Every year after age 65
The DVA may also request additional medical assessments depending on your individual medical history or licence circumstances.

Preparing for Your Medical

Most drivers pass their DLM1 medical without any problems. To help your appointment go smoothly:
  • Wear your usual driving glasses if required.
  • Bring all requested paperwork.
  • Know the names of your current medications.
  • Stay well hydrated.
  • Avoid rushing immediately before your appointment, as this may temporarily raise your blood pressure.
