Same as it is with cars.. in countries which drive on the right side of the road (USA, Canada, Mexico, all of mainland Europe, etc.), the steering wheel is placed on the left side of the vehicle. In countries where they drive on the left side of the road (United Kingdom, Ireland, South Africa, Zimbabwe, Australia, New Zealand, Japan, Jamaica, etc.), the steering wheel is placed on the right side of the vehicle.
No.
Situation dependent.
Of course. The NJT is full of 18 wheelers.
If you are talking about two wheelers, as in motorcycles, minors should not be given two wheelers to drive. A minimum age of 18 should be required since younger kids may not be responsible enough to make wise decisions when riding.
Yes, 18 wheelers have 18 wheels.Some tractor trailers have more, some less.
Depends on the state law, most states do not allow big trucks in the left lanes of 3 lane or more highways at 65mph or higher.
The statistics are not broken down by that category (i.e.: 18-wheelers, 10-wheelers, 6-wheelers, etc.). They are all classified as "commercial" vehicles.

Yes
Steel or aluminum.
