- DDeclare it at the next Driver CPC periodic training course
Answer: A driver must tell the DVLA themselves, online or by post, about any notifiable medical condition or disability, or one that has got worse, that could affect safe driving, and should also tell their insurer, because an undeclared condition can invalidate cover. Failing to tell the DVLA can lead to a fine of up to £1,000. The legal duty rests with the driver, not with an employer or GP.
