Garter snakes are common North American snakes that pose little threat to humans. The pattern on these snakes consists of one, two or three longitudinal stripes on the back, typically red, yellow, blue, orange or white. Constrictors are also of little danger to humans, so long as they aren't big enough to wrap around a person multiple times. Many small snakes are not dangerously venomous to humans.
