Finding out why something has stopped working, and putting it right.

The vehicles are bigger, so the mistakes are more expensive.
Will machines take this job?
Hard for machines to take over. Diagnostics increasingly come from software, but the repair itself and the judgement about what is safe do not.
How to find out whether it suits you
Visit a haulage workshop and ask to see a fault diagnosed from start to finish.
Would this actually suit you?
