Yes, you can add a named driver to your van insurance policy. Named drivers are individuals you permit to drive your van, and including them can be beneficial if they have a good driving record. However, adding a named driver may influence your premium, either increasing or decreasing it depending on their driving history and experience. It's best to check with your insurance provider for specific terms and how it may impact your coverage and costs. Always ensure the named driver is adequately insured to drive your vehicle.
