In case of late return of the car, you have to warn the owner as soon as possible. If you know you will be late to give the car back, make a request to extend the rental, otherwise you will not be covered by our insurance. The insurance only covers you for the current half-day (till noon for rentals ending in the morning ; till midnight for rentals ending in the afternoon).
Your request can be approved or declined.
If the extension is approved: The amount of the rental will be automatically adjusted and you will benefit from the insurance coverage.
if the extension is declined, or the owner can't approve it: You'll have to return the vehicle at the date and hour originally planned.
If you return the vehicle later than expected, you'll owe late return compensation fees:
5€ per hour up to 120€ for 24h late
30€ of compensation fees for each additional day
You will also have to pay of the eventual additional days and adjustments for gas and distance. After the end of the half-day when the end of the rental was planned, you won't benefit from the insurance coverage and any damage on the vehicle would be completely on you.
