If you were under the age of 21 when you acquired a category T driving licence, the maximum authorised mass must not exceed 25,000 kg for a single vehicle or vehicle combination. The weight limitation lapses when you have two years’ experience of using a category T driving licence or you have reached the age of 21.
A Category T driving entitlement also entitles you to drive a three- or four-wheeled moped. If you are under 18 and obtain a licence for Category T tractors, you are entitled to drive three- and four-wheeled mopeds with a weight restriction of 150 kg. To indicate this entitlement, Code 149 is entered on your licence card. When you turn 18, the weight restriction is cancelled and next time a licence card is issued to you it will carry T Code 147.
Even if you are not yet 18, you can extend your licence from Category T149 to T147 by taking the safety course on the road for Category AM147. This will entitle you to drive three- and four-wheeled mopeds in Norway. In order to obtain a driving entitlement that is also valid outside of Norway, you need to pass the theory test for AM 147.
Category T also confers driving entitlements for category M 147 (three-/four-wheeled moped) and for motorised equipment (with or without a trailer) that is not designed for the carriage of passengers or goods, and that has a maximum speed of 30 km/h.
Category T also confers driving entitlements for:
all tractors or motorised equipment with or without a trailer when category T was acquired before 1 January 2005
category S when the driving licence was acquired before 1 July 2006
The definition of category T is new as of 1 January 2005. Category T acquired for the first time after 1 January 2005 only confers driving entitlements for tractors with a maximum speed capability not exceeding 40 km/h. If a person wishes to drive a high-speed tractor (exceeding 40 km/h), the maximum authorised mass of the tractor must be checked to find out whether category B, C1 or C is required (i.e. whether the maximum authorised mass is 3,500 kg, 7,500 kg, or more). If you are going to tow a trailer with a maximum authorised mass exceeding 750 kg using a high-speed tractor, category BE, C1E or CE is required. The same applies to the driving of motorised equipment with a maximum speed capability of over 40 km/h.
Driving entitlements acquired before 2005
Persons who acquired driving entitlements for tractors before 2005 do not have to check the maximum speed of the tractor. The only requirement is that the vehicle is registered as a tractor (the entitlement is now covered by code 142.) The same applies to driving entitlements for motorised equipment if you acquired category 1 or 2 (green driving licence) before April 1979, or if you acquired category C1, C1E, D or DE for the first time during the period 1 April 1979 – 1 January 2005 (the entitlement is now covered by code 140.) If you acquired category B, BE, D1, D1E, D2 or D2E during the period 1 April 1979 – 1 January 2005, you can drive any motorised equipment with a maximum authorised mass not exceeding 7,500 kg, and motorised equipment with a higher maximum authorised mass, provided that the maximum speed capability of the motorised equipment does not exceed 50 km/h (the entitlement is now covered by code 152.)
If you acquired category C or CE during the period 1 April 1979 – 1 January 2005, you can of course drive any vehicle registered as a tractor or motorised equipment.
