If you do not drive on Safe Families or Home for Good business and therefore have no need to record motoring documents, you or your line manager can mark you as a non-driver and prevent reminders being sent.
On the Motoring Documents page, press the Mark as Non-Driver button
A note will be added and the page will reload. The button will toggle and will now allow you to mark the employee as a current driver.
The change will also be reflected on the Team >> Motoring Documents view.
