In the UK, drivers reaching 70 years old will lose their C1 and D1 driving license entitlements unless they take specific actions to retain them. The Older Drivers' Forum has highlighted that renewing a driving license at this age means drivers must apply for these entitlements separately. If they opt for the standard online renewal, they will automatically lose their ability to drive larger vehicles, such as motorhomes weighing between 3,500kg and 7,500kg, unless they pass a medical examination. To keep their C1 and D1 entitlements, drivers must submit a D4 medical report every three years, which needs to be filled out by a doctor or a private medical firm. This process incurs additional costs. It's important to note that drivers who do not wish to go through the hassle of a medical exam can choose not to renew these categories, but their new license will simply exclude them. However, all standard car and light vehicle categories will remain intact.
