Bigger than average

Normally, 110 inches.
If you're talking about the trailer door, you move the metal latch up, move the handle up then left or right, depending on what door until the door is unlocked, move it back into the holder and latch it on side of the trailer.
Depends on the complete trailer dimensions. Trailer width would either be 96 or 102 inches, trailer height varies considerably - if it's a typical 13'6 high cube van, then you'd be looking at 110" inches from the trailer floor to the ceiling.
Are you talking about door for the cab? Because there is no universal standard - there are many makes and models of power units, each with their own door style.
This suggests that your personal matters are not secure. The tractor trailer symbolizes yourself on your journey through life, together with the sense that you are carrying a heavy "load" or "baggage." Having the door open - assuming it is the door of the trailer - leaves open opportunity for theft or loss. On the other hand, if it is the door to the cab that is open, perhaps you are waiting for a partner or even for a driver, suggesting that you want or need someone else to control your life.
There'll be a sticker inside the door frame on the driver's side with this information on it.
A number of ways. Sometimes, it's a straightforward hijacking, where the driver is effectively kidnapped. Other times, they might simply use a set of keys... Freightliner, for instance, only has six or so different key designs.. if you ever locked your keys in your truck at a truck stop or customer, you could almost always be guaranteed to find someone in that lot who could open that door for you.
Gross Vehicle Weight Rating, or GVWR is the rating given to a vehicle by the manufacturer. It can usually be found on the door pillar post (open the door and look for the sticker). Gross Combination Weight Rating is normally the weight assigned to a power unit (Truck Tractor) when speaking in terms of the weight of itself and the trailer. GCWR most generally would be 80,000 lbs., for a standard over the road truck configuration.
Refrigerated trucks come in all shapes in sizes, from Class 1 pickups used by vendors selling meat door-to-door all the way up to Class 8 tractor-trailers.
The gross trailer weight should not exceed the GVW of the tow vehicle. Check the sticker on your drivers door for the GVW (Gross Vehicle Wieght) of your truck. Trailer brakes would be highly recomended.
