I buy some carrots and banana from grocery store and put them in my car i forget to take them out they sat in the car whole night in tightly tie plastic grocery bag in morning i saw them should they safe to eat now?

Yes, entirely safe. The carrots and bananas grew at room temperature or even warmer; they probably were not refrigerated at the grocery store; and they do not need refrigeration to stay safe.

Fresh vegetables such as carrots And bananas generally are fine at room temperature. As long as the conditions inside the car we’re not extreme, your fruits and vegetables should be just fine. Good luck.
