When you sign up, you can specify a second driver at the very first stage: this must be the person who will drive the vehicle most often after you and for at least 24 days a year - whether it is your wife, husband or child.
Please note that if that second driver is 25 or older, they will be insured in any case, even if they are not named as a driver in your contract. Therefore, you don't need to inform us.
If other people drive your vehicle more occasionally, they will still be insured in case of problems without you having to send us any documents or information. As long as the driver of the vehicle has a valid driving licence and is a resident of the country.
