With a normal drivers license (type B), you can drive any type of trailer with a total weight of 750 kg. or less if your car is allowed to carry a trailer with the given weight.   A box trailer and an open trailer at Freetrailer weigh 750 kg.  Our open 2-axled trailer weighs 1300 kg. In this case the vehicle and trailer must not weigh more than 3,500 kg in total – if you have a normal driver’s license. Your car can therefore not weigh more than 2200 kg. If you have an extended driver’s license, you’ll be allowed to drive with more than a total of 3500 kg.
