I am a sales representative and consequently travel frequently from Melbourne via Adelaide through to Darwin.

It is hard enough travelling slow and combatting fatigue but now I have to worry about speed limits and passing road trains within those limits, which I might add, is impossible to do safely without the risk of getting a fine.

In future, because of speed limit restrictions I will fly now only to Alice Springs and Darwin to avoid these dangerous restrictions.

As a result, regional towns will now miss out on money that I would have normally spent when going through these towns.

Unfortunately Tennant Creek and Katherine will miss out the most with this stupid law.
