Mary Peltola was on her way to a campaign event with her family on Saturday when the accident occurred.
Her campaign manager said in a statement that Peltola was in "good spirits" after the accident, but that her doctor had recommended she cancel her planned events on Sunday and Monday.
Former Congresswoman Mary Peltola has challenged incumbent Republican Senator Dan Sullivan, hoping to become the first Democrat in nearly two decades to represent Alaska in the U.S. Senate.
President Donald Trump has said the government will prevent the outcome of the Senate election from being determined if the Republican candidate loses.
