probably, but since you need a special driver license to drive a combination with MTM higher than 3.5t, I guess most car + caravan are below that. A car + small trailer (typically under 750kg) can also do 120.
AFAIK, this is also true for France.
Unlike in Germany where caravans(or with any trailer behind your car) can only do 80 unless car+caravan gets a special inspection. Then they can do 100.
