From 7 November 2025, the Driver and Vehicle Licensing Agency (DVLA) has updated its rules to allow bus, coach, and lorry drivers with diabetes to use Continuous Glucose Monitoring Systems (CGMS).

These devices use sensors to provide real-time glucose readings, replacing the previous requirement for finger-prick blood tests before and during driving.

This modernisation brings professional drivers (Group 2 licence holders) in line with car and motorcycle drivers (Group 1), who have been permitted to use CGMS since 2018.

The change aims to make it easier for drivers to monitor their glucose levels safely and effectively while maintaining high road safety standards. Drivers must still stop safely if they need to verify their readings.

DVLA Chief Executive Tim Moss CBE described the update as a step towards improving the lives of professional drivers while keeping roads safe.

The change has been widely welcomed by health experts and industry representatives, including Diabetes UK and the Road Haulage Association, who say it will help drivers manage their condition with greater confidence.

The decision follows a targeted consultation in which 89% of respondents supported the move.
