Sweden's Transport Agency (Transportstyrelsen) reminds drivers that those who obtained a B category licence before 1 July 1996 may drive a heavy motorhome (over 3500 kg) without a truck licence. This exemption, known as the 'grandfather rule', is permanently lost if the licence is revoked or becomes invalid for any reason, including medical, even for one month. After revocation, driving a motorhome up to 7500 kg requires a C1 category, and heavier ones require a C. Similarly, older rights for extra heavy trailers (BE taken before 19 January 2013) and four-wheeled motorcycles (A or A1 before the same date) are lost. A fine or warning without revocation does not remove the exemption. The date on the back of the licence does not prove the old privileges remain — they can be checked in the road traffic register.
