When someone tends to have a lot of accidents, you can describe them as "accident-prone":
Yolanda? She's very accident-prone. She's always bumping into things, dropping things, you name it.
Being "accident-prone" is a little different from being "clumsy". A "clumsy" person isn't very good at moving their body.
I could never be a dancer. Way too clumsy.
Someone who is "accident-prone" could have a lot of accidents because they're clumsy, or it could be because they're not careful. Or it could just be bad luck.
