Yes they may, but you must first have them sign up for an account with Flux as we need to have their information added to the Flux database and our insurance partner’s records. Once they have signed up, please email our Customer Service team at support@driveflux.com, informing them you would like to add an additional driver to your car subscription. You can have only a maximum of 3 additional drivers added to a subscription. Please note, unregistered friends and family members will not be protected by your Flux insurance.
