The "easiest" way to tell is to read the label on the glass.

.... if legible, it will be in one of the corners, check inside and out, sometimes they are too faint to see through the glass..... Laminated glass will have something like "Lami" in the description... "Securx" or something like that would be tempered.
In absensce of a label, tempered glass usually have tong marks (dimples) along one edge of the glass. These were made from where the glass was hung while going through the tempering oven (tong marks are only on tempered glass made during the '70s and earlier).
Last method of detection, if the other aren't a dead giveaway is to take your
fingers and peel back the gasket at some place and look at the edge of the glass inside the gasket. Tempered glass will be obvious as a single piece of glass, and with laminated glass , you will see the 2 actual pieces of glass and the plastic interlayer.
Do not consider tempered glass as a " less safe" type of windshield...it is completely unsafe on any high speed vehicle where wind force can push the shards into the passenger compartment like a claymore mine
.
