What is the most exciting aspect of driving an 18-wheeler truck across America (or any other country)?

All heavy vehicles (over 12,000 kg max weight) are limited to 100kmh (62 mph), even where the speed limit is higher.

In Australia we have 22 wheel trucks as standard - three axle trailers.

We use both Cabover and long bonnet trucks. I drive a nice Scania Cabover with 560hp and a 12 speed auto-changing gearbox. Comfortable and easy to drive after years of old Western Stars, Kenworth and Ford L9000s with 13 and 18 speed manual gearboxes.

it takes around three days to drive Adelaide-Darwin, or around four days to drive Sydney-Perth.

Our trucks have big horsepower (kilowatts), and big fuel tanks to cope with the long distance.

And we have up to three trailer road trains (53.5 metres long) on some more remote roads. I have that licence, though I am usually towing Bdoubles or two trailer road trains.

With a Fatogue Management Certificate, that 12 hour work day can extend to 14, but with very strict rest break requirements.

Towns are few and far between so there are roadhouses in some remote areas to fill in the gaps.

We have to have enough technical knowledge to make some repairs on the road.

We have unfenced roads in many locations so have to watch out for roaming kangaroos, emus, sheep, and camels.

We allow higher weights than US trucks - 42,500 kg (93500lb) versus 80,000 lb for a single trailer semi.
