The Poll

92% of ordinary working people agreed in a recent D4Drivers poll that sight is the most important sense in the body. Additionally, unsurprisingly 97% of those we asked who ticked HGV or PCV driver as their profession in the survey recognized this statement.

When driving heavy goods or passengers your eyesight must be at a satisfactory level for the DLVA to allow you to drive and this is tested in a D4 Medical along with several other things (these can be found here) Many drivers don’t realise their eyesight has slipped below the level required and subsequently fail their medical. However there is no need to worry if you think your eyes aren’t what they used to be or if you wear glasses for driving, as we have compiled a list of our top reasons why your eyesight may not be up to standards and what you can do to improve and ultimately pass your medical on the day:

  1. Visiting your opticians:

    When driving frequently and for long periods it helps to keep on top of your eyesight by visiting your optician/optometrist regularly and many of us are guilty of going without a check up for months and sometimes years longer than we should. Opticians will know if your eyesight has deteriorated and what to do to correct this for the roads.

    For a D4 Medical you need to know your driving glasses prescription so why not have an appointment when you go in to your opticians to find out your prescription. Even if you do not wear driving glasses it will still pay to have your eyes checked, especially before your medical is due.

  2. Smoking:

    A relatively unknown risk of smoking is the damage it can do to your eyes, making cataracts, optic nerve damage and macular degeneration all more likely. This is another reason to quit smoking, reducing your chances of associated diseases and increasing your chance of passing your D4 Medical.

    For all other reasons aside not smoking means one less distraction in the cab when driving at high speeds.

  3. Limiting screen usage:

    Concentrating on the roads for extended periods of time compared to the average person can begin to make your eyes ache, to then go and look at phone and computer screens when taking the required break can start to strain them further. Continually doing this can cause irreparable damage.

    In this day and age looking at screens is unavoidable but you can do things to help. For one turn the brightness down, this will reduce your eyes being dazzled by the light, also try to reduce the time spent looking at a phone or computer screen. For every 15 minutes spent looking at a screen 10 minutes should be spent relaxing your eyes.


We hope this advice helps when the time comes to renewing your medical, or having it in the first place before you gain your provisional licence.
