Category C+E refers to a specific driving license classification in the United Kingdom that allows individuals to operate large vehicles. This category is primarily for drivers who wish to drive vehicles over 3.5 tonnes with a trailer exceeding 750 kg. It is essential for those looking to work in industries that require transporting goods or materials. To obtain a Category C+E license, drivers must first hold a Category C license, which permits driving large vehicles without a trailer. After that, they must pass additional tests, including a practical driving assessment, to demonstrate their ability to handle larger combinations of vehicles safely.
