Group 1 vehicles include cars (B categories) and motorbikes (A categories). Group 2 vehicles include trucks (C categories) and buses (D categories)
The categories of vehicles are set at European level. The EU Driving Licence Directives, on which national legislation is based, set out the requirements for obtaining a driving licence in each category, such as age limits, fitness to drive and training and testing standards. Applicants for a category of licence that comes under Group 2, which includes category C1, are required to meet a higher level of training and testing, and must provide a medical report to support their fitness to drive.
