My boss called me a rude name!

If your boss…who is presumably your line manager, behaves in any way that compromises your well being or your right to work in a reasonable environment ( that is free from abuse) then take a breath, sleep on it if necessary and then email him confirming the conversation that you had with him.
If after a while it becomes excessive then you will have a good record of what you have had to put up with…useful if you take them to a tribunal.
This isn’t the Victorian times and haulage employers will continue to suffer if they don’t get with the programme…that means going out of business if they don’t treat drivers with a basic degree of respect and show due care and diligence…
