Its a garter snake wich is harmless they have those colors because theyve been in the shade for a long time.
Your description is very vague ! Depending on how the stripes are arranged - it could be a Ribbon snake, Garter snake or Mangrove snake !
If the stripes are light in color, maybe even off white it could be a CA king snake.
Garder-snake; multi color green, yellow and black stripes length of body.
Can be either a coral snake or king snake. They look very similar, but the coral snake is one of the moat deadly poisonous snakes around. Best to leave it be.
Sea Kraits are white with black stripes. Or black with white stripes if you like to look at it that way.They're a sea snake, highly venomous, but only aggressive when provoked repeatedly.King snakes are also black and white, striped. They are non-venomous, land based and eat other snakes.Hope this helped!

The Speckled King snake is a black snake with yellow or orange spots speckled over it's body. Another black snake with yellow spots would be Baby Eastern Black King Snake. Both are completely black with yellow speckles.
Garter snake
blackish brownish snake
I believe you are refering to a black rat snake.
Answer Depending on the order of the stripes and the area where you live it is either a coral snake or a type of milk snake. I have just googled this because of a snake on a TV advert (in the UK). I reckon it could easily be a corn snake. They aren't actually stripes, but really look like stripes.
