The validity of an HGV medical depends on your age and, in some cases, your medical history. Many drivers often ask: “How long does my D4 medical last?” Understanding this is essential to ensure your licence remains valid and you stay legally compliant.
The D4 medical form is required for all Group 2 licence holders, which includes:
Once your medical assessment is complete, you have four months to send the D4 form to the DVLA. If it’s not submitted within this timeframe, you will need to undergo a new assessment. Many drivers forget this step, so it’s crucial to submit the form promptly.
HGV medical renewal depends largely on your age:
For example, if you apply for your licence at age 43, your first medical covers you until your 45th birthday—so your next assessment is just two years later. After that, routine check-ups are required every five years until you turn 65, then yearly.
Some drivers with certain medical conditions may need more frequent medical assessments. The DVLA will notify you if this is necessary once you report your condition. It’s a legal requirement to declare all notifiable medical conditions to the DVLA, so always consult your doctor if you’re unsure whether your condition needs to be reported.
Not every renewal form means you need a medical. Many younger drivers in their 20s or 30s are surprised to find they don’t require a D4 when they receive a renewal notice. Always check the guidance on the form—there’s usually a note in the top right corner indicating whether a D4 medical is required. Paying for a medical you don’t need is unnecessary.
By understanding these timelines and requirements, you can avoid unnecessary delays, extra costs, and potential legal issues while keeping your HGV licence valid.
