Thanks for your replies everyone, much appreciated.
I think my point was slightly taken the wrong way, I would have no intention of blagging my way into a job miles and miles from home and commuting each day, I fully understand the reasons for the rule and completely agree that safety is of paramount importance.
What I meant was at application stage, many companies have the question on the form and if you tick no, stating that you live outside of their allowed commuting time, you can't apply.
Where I live, there is only one TOC within range, limiting my chances severely of ever getting a job. I have no ties and could (and would) relocate immediately to as close to the depot as I could find prior to even starting the training.
I can't move house and leave my current job to an area where a TOC might advertise on the basis that would allow me to apply, when I may not even clear the application stage! But as I said, I am prepared to move anywhere for the job once offered a position.
I'm not a liar and I fully understand the safety aspects of this role. I know others have got jobs that were miles from where they live so I just wondered how they'd by-passed this little issue.
