Congratulations on achieving your C licence, and hopefully your artic will be as quick in coming.
You’re in a catch 22 situation that can exist when the market is quite tight as it is right now.
The best way forward is to offer your services for a very cheap rate, or even free, in return for some rigid driving experience. Most hauliers will only be too happy right now to pay slightly less rate. You will only need a couple of months experience, before you can put this on your CV, and on applications for other work. It’s also easier to get a job from a job.
Investigate your contacts and see if you can find a way into a haulage firm at a lower rate to get your foot in the door experience-wise.
