Towing a trailer or caravan increases your vehicle’s length, weight, and stopping distance. Swedish law sets strict limits on what you can tow and how to do it safely.
Maximum Towing Weights
Every vehicle has a maximum towing capacity specified by the manufacturer. This is recorded in the vehicle registration certificate. You may never exceed this limit. The trailer’s maximum gross weight (including load) must also not be exceeded. In general, a trailer heavier than the towing vehicle is restricted to lower speeds.
Speed Limits When Towing
When towing a trailer in Sweden: maximum 80 km/h on all roads unless the trailer is approved and the combination meets specific criteria allowing up to 90 km/h. Even where higher limits are posted, the towing limit applies. This is a common exam question — the answer is 80 km/h as the default towing limit.
Trailer Requirements
Trailers must have functioning lights (tail, brake, indicators), a number plate matching the towing vehicle, and a tow hitch in good condition with a safety chain as a secondary connection. Trailers over a certain weight require their own braking system.
Exam tip: The default maximum speed when towing a trailer in Sweden is 80 km/h — even on a 120 km/h motorway. This is frequently tested.
