There is a minimum age for drivers of large trucks? if the answer is yes.. how many?

Hi, I just got to get the truck license in Spain and want to move to London. How do I find out if I’m allowed to use the same authorization in both countries?

The role of a hgv driver requires long hours on the road and is ideally suited to someone who doesn’t mind being alone and working on their own initiative. The purpose of the job is usually to deliver heavy goods to manufactures, retailers, wholesalers and other businesses nationwide or on an international basis.
Day-to-day duties include keeping detailed reports of mileage, fuel use and other costs incurred while on the job. A hgv driver must have a patient personality as they will often have to wait in heavy traffic or sit for sustained periods behind the wheel.
All drivers are required to have special type of license to drive a heavy goods vehicle. The average salary for this type of work varies from region to region but the typical range is around £18,000 per year in the UK. Some driver can make up to £20,000, depending on experience.
