The correct following distance for a tractor-trailer is typically at least four to six seconds behind the vehicle in front of it. This distance allows for sufficient reaction time, considering the larger size and weight of the truck, which requires more time and distance to stop safely. Factors such as road conditions, weather, and traffic speed may necessitate an even greater following distance. Always prioritize safety by adjusting your distance based on the driving environment.
You always want to ensure that you are far enough back that you can see the mirrors of that tractor - this also ensures that the driver can see you.
The Explosives 1.3 placard may be placed on either the front of the tractor or the front of the trailer

I would have to say no. I have a tractor that is insured the only thing that is insured is just that the tractor (fire theft etc). Although You can get your trailer insured just as you can an ATV horse trailer car truck if you had a policy for it. your tractor insurance will not help with the trailer.
semi truck, or semi tractor trailer, and 18 wheeler.
A bobtail truck is a truck that is not carrying anything. It has no trailer or chassis connected. It is usually the tractor part of a semi truck without the trailer. It can also refer to a truck where all of the axles are connected to the same chassis.
Depends on what type of tractor and trailer you had in mind. For a farm tractor pulling a trailer, it's usually a pintle on the tractor which is run through a clevice on the trailer. For road going vehicles, the fifth wheel trailers are often used, where a trailer kingpin will be inserted and locked into a fifth wheel on the vehicle. In the case of an 18 wheeler, air lines will connect from the tractor to the trailer to operate the trailer's air brake system.
Semi or Tractor Trailer-semi.
An 18 wheeler consists of a tractor (meaning something that pulls) and a trailer (meaning something that follows.) A semi tractor-trailer rig has a trailer that sits on top of the frame of the tractor on a coupling device called a "fifth wheel." The tractor has ten wheels with two on the front axle and four on each drive axle in the rear. The trailer has two axles with 4 wheels each. The tractor and trailer together are informally called a rig. Is that what you were after?
