Failing your taxi medical can delay your licence application and slow down your ability to get back on the road. At Essential Medicals, we regularly see drivers who could have passed their medical if they had been better prepared before attending their appointment.

Taxi medicals are required by most local councils and must meet DVLA Group 2 medical standards. These standards are in place to ensure all licensed drivers are medically fit to operate safely when transporting members of the public.

Below are some of the most common reasons drivers fail their taxi medical and what you can do to improve your chances of passing.

High Blood Pressure

One of the most common reasons for failing a taxi medical is high blood pressure.

The cut off for blood pressure during your assessment is 180 over 100. A reading at or above this level on the day of your appointment will result in a failed medical.

If your blood pressure is too high, it does not necessarily mean you cannot become a taxi driver. You may simply need treatment from your GP before returning for another assessment.

To prepare for your taxi medical if you have high blood pressure:

  • Monitor your blood pressure at home in the weeks before your appointment
  • Take your prescribed medication as directed
  • Avoid caffeine and nicotine on the day of your medical
  • Bring a record of your home readings with you

This can be especially helpful if you experience white coat hypertension where your blood pressure rises in a clinical setting.

Heart Conditions

Cardiac conditions can affect the outcome of your taxi medical if they are not properly monitored or documented.

Conditions that may require further review include:

  • Angina
  • Heart attack history
  • Heart failure
  • Previous cardiac procedures

If you have a history of heart issues, you should bring supporting medical evidence such as:

  • Hospital discharge letters
  • Cardiology reports
  • Echocardiogram results
  • Exercise tolerance test results if available

Providing full documentation allows the examining doctor to assess your fitness to drive safely and may help prevent delays in your application.

Vision Requirements

Eyesight is another key part of the taxi medical assessment.

To meet Group 2 standards, drivers must have visual acuity of at least:

  • 6 over 7.5 in one eye
  • 6 over 60 in the other eye

This standard applies to corrected vision, which means glasses or contact lenses can be worn to meet the requirement.

Before your appointment:

  • Have an up to date eye test with an optician
  • Bring your glasses or contact lenses
  • Make sure your prescription is current

If your eyesight does not meet the minimum standard, you may not pass the medical until this is corrected.

Diabetes Management

Many drivers with diabetes pass their taxi medical without any issues. However, certain medications require additional monitoring.

If you take medications such as gliclazide or glimepiride, you may need to provide 4 to 6 weeks of blood glucose readings. Without these readings, you are unlikely to pass your assessment.

To prepare:

  • Monitor your blood sugar levels regularly
  • Bring your glucose monitor to the appointment
  • Provide a list of your current medications
  • Bring recent blood sugar logs

Drivers taking metformin alone will usually not need to provide blood sugar readings.

If you use insulin, further specialist input may be required before you can meet the medical standards for driving.
