Venomous or Non-Venomous
How are you supposed to Know?
If you aren’t sure just give the animal space. In the United states it is a short list. Rattlesnakes, Gila monster, Copperheads, Cottonmouths, and Coral snakes.
Anywhere in the world if you aren’t sure giving the animal space will help keep you and the animal safe.
Some snake species are venomous so snake leg guards can be used in situations where you may be traveling through risky terrain. In the US this would mean arid habitat that may have a large amount of thick grass that makes it difficult to see exactly where you are putting your feet.
There are many good guide books that can help you identify species. These are typically organized by body morphology snake, lizard, turtle etc.
