If you are at one of our partner locations and can book a free Freetrailer, the first rental period is always free.To make a free booking at our partner locations, your location service must be switched on.It is optional if you choose to purchase insurance. To borrow completely free of charge, you must opt out of insurance. The rental period is no later than the next day when each partner opens for rental (most locations at 7:00 am), if the trailer is not booked for others. It is possible to have one free rental period per day.
