If you are keen on driving the large vehicles or the heavy goods vehicles, you can always check out the LGV/HGV training. Some of the categories in this regard are the C1 license, C1 + E – license, C1 + E 7.5t + trailer, C up to 32 tons and C + E truck & trailer. Of course there is also another dependent factor and that is of the weight specifications of the vehicles.
The B+E car and trailer training is meant for driving the towing vehicles only and for that, the dependent factor is the MAM or the maximum authorized mass. When the vehicle is within the MAM category, you should apply for the B license, when the vehicle is more than the MAM limit, you should apply for the B+E license.
