Here you go - this link describes most of the tankers used for hazmat transportation.

 

In general, MC-306 and DOT 406 tankers are elliptical when viewed from the rear.  By far the most common product carried in them is gasoline or other flammable liquids.  They usually have a heavy, built-up top that is hollowed out to contain small spills.  These tankers have one or more domes and dome covers, generally one dome per compartment in the tank.

 

MC-307/DOT 407 tankers are a usually a horseshoe shape when viewed from the rear.  They carry vegetable oils, syrups, and milk - and they also carry solvents, lubricants, mild corrosives, etc.  The horseshoe shape tanks are insulated - the shape you see is the thin aluminum insulation shell cover.  Some of these tankers are uninsulated, appear round with small ridges, and are usually unpainted aluminum if un-insulated.   The domes in these tankers are usually in the center of the long axis of the tank, but can be multiples or in other locations.

 

Don't confuse the 307/407 tanks with the MC-312 tankers.  The 312's are almost always small-diameter round tanks made from steel, and with many rings running around the tank for strength.  These tanks usually have a loading box at the rear and the loading area is almost always discolored and etched from corrosive spills that occur during loading. 

 

There are other types, but these three classes are all fairly common.

 

Good luck as a hazmatician.

I have a bunch of pictures and powerpoints of various otr and fixed tanks if youd like me to send you some.

The 306 tanker will always be in the oval shape and will have the rollover protection ridges on the top of the tank. It can have several separate compartments, which are identified by the valves at the bottom or how many fill ports at the top. This is generally so different grades of fuel can be hauled at the same time, The 306 is also an aluminum tank and is not insulated, so any damage you see is to the tank itself.

The 307 is generally insulated like Ben said but you may see one during transportation without the aluminum insulating. (Although it is rare) If you peel the insulation away it looks similar to the 312 corrosives container but has a larger circumfrence than the 312. Being insulated, any visible damage you see may just be to the outer shell and not to the tank itself, which can make it a bit more difficult at times to determine what the damage to the tank is.
