I'm 17, so a few years yet! I just like the idea of being king of the road! Cruising along seeing the country and others possibly with music playing in a nice warm environment!
Can i ask if you have a wife and kids? My mates dad used to be/is a lorry driver, and he has kids n wife, they were a happy family (when he was around, mind)!
I am divorced, I have an 11 year old daughter. - We divorced when she was 17 months old - I was never home and the ex ended up with somebody else.
Same thing happened again to me a few years later,different relationship - same situation, I was away 4 - 5 nights of the week and things were happening whilst I was away.
Thats just it with being a professional driver, especially on general haulage / distribution work, you are rarely around to see the wife & kids, which is why so many truckers are divorced / un-married or single.
You can take your BMW's , Porsches, Ferrari's & shove them, You are the King of the road, as long as you appreciate that many fellow road users don't realise this, or, choose to ignore it completely!
A DAF, Scania, Volvo FH etc is a nice place to spend your time, some would say the same goes for Women / family life.
Take your pick - you rarely get both in this job.*
* Parking up near Avonmouth docks for example gets you plenty of Women, normally they want your "Business" though.
