Co mply withthe maximum speed of 49 mph
(80 km/h) or 62 mph (100 km/h), even in coun‐
tries in which higher speeds are permitted for
ve hicle/trailer combinations.
Comply with the legally prescribed maximum
speed forve hicle/trailer combinations in forc e in
th e count ry,st ate or Canadian pr ovince in ques‐

documents tosee the maximum permissible
speed foryo ur trailer.
At tach only an appr oved trailer hitch to yourvehi‐
