The D4 medical is the standard DVLA health examination required for all Group 2 driving licences, including HGV, LGV, and PCV. Whether you’re applying for the first time or renewing, our GMC-registered doctors complete your D4 form during the appointment and hand it to you the same day — from just £55.
Understanding DVLA D4 Medical Requirements
The DVLA D4 medical examination is mandatory for all professional drivers seeking to obtain or renew Group 2 driving licences. This health assessment ensures drivers meet the medical standards required for safe operation of large commercial vehicles and passenger transport across the UK. Our GMC-registered doctors conduct examinations following current DVLA guidelines, with same-day D4 form completion from £55.
What the Examination Covers
Your D4 medical includes a full medical history review covering existing conditions, medications, and family history. The physical examination covers cardiovascular assessment with blood pressure monitoring, neurological examination including reflexes and coordination, and musculoskeletal evaluation. We check for conditions that could affect driving safety, including heart disease, diabetes, neurological disorders, and respiratory conditions.
Vision Testing Standards
Professional drivers must meet enhanced eyesight requirements. We test distance visual acuity, peripheral vision, and colour vision for traffic signal recognition. If you wear corrective lenses, we test your vision with and without them. You must be able to read a number plate at the statutory distance of 20.5 metres and clearly distinguish traffic lights and road signs.
Managing Health Conditions
Drivers with diabetes need adequate glucose control and hypoglycaemia awareness — bring your HbA1c results and monitoring records. Heart conditions including previous cardiac events or angina require stability and may need specialist reports. Sleep apnoea requires evidence of effective CPAP treatment. We work with your existing healthcare providers to ensure DVLA compliance.
D4 Form Completion
We complete your DVLA D4 form during the appointment with accurate medical findings. Both doctor and applicant signatures are obtained, with same-day form completion. The completed D4 form is submitted to the DVLA Drivers Medical Group in Swansea as part of your licence application or renewal.
Certificate Validity
Drivers under 45 typically receive five-year medical certificates. Drivers aged 45–64 receive certificates valid for up to five years. Drivers over 65 require annual medical reviews. Certain health conditions may require more frequent assessments regardless of age.
