Recent reports have highlighted new Ministry of Defence (MOD) guidance for staff using electric vehicles within the military transport fleet. Stickers have been placed inside these vehicles reminding personnel not to connect official devices to in-car systems and to avoid discussing sensitive information while travelling.
The advisory notices follow assessments by the Defence Science and Technology Laboratory (DSTL), which found that modern connected vehicles, regardless of manufacturer, can present potential information-security risks due to the complex digital systems they rely on. Importantly, there is no evidence of any data being compromised. The MOD has reiterated that these precautions are part of its routine, ongoing commitment to information security across all civilian-hire vehicles.
As the MOD moves towards a net-zero vehicle fleet, these practical measures reflect the growing digital complexity of transport platforms. With more connectivity comes a greater need for clear labelling, strong procedures and reliable reminders that help staff follow best practice.
