§ Country Overview & Administrative Framework

DVLA Medical Fitness Assessment: Form D4, Declaring Conditions & Vision Standards

Under Section 92 of the Road Traffic Act 1988, all drivers in Great Britain have a strict legal duty to declare any medical condition that could impair their ability to drive safely. Failing to notify the DVLA of a notifiable condition is a criminal offence punishable by a fine of up to £1,000 and may invalidate your motor insurance coverage in the event of an accident.

Key statutory medical frameworks include :

  • Group 1 Licences (Cars & Motorcycles) : Conditions that must be declared include epilepsy, seizures, diabetes treated by insulin, stroke with residual impairments, severe head injury, visual impairments, and cardiovascular issues ;
  • Group 2 Licences (Lorries & Buses) : Governed by vastly higher medical criteria. Applicants must undergo a comprehensive medical examination conducted by a registered general practitioner using Form D4 ;
  • Vision Standards : All drivers must be able to read a standard number plate in good daylight from a distance of 20 metres and have visual acuity of at least 0.5 (6/12) on the Snellen scale with both eyes open.
