Police in Australia said a woman was forced to fend off a deadly tiger snake in her vehicle while driving 50 miles per hour on a freeway outside Melbourne.

Police officers responded to reports of a barefoot woman trying to flag down vehicles on the side of the Monash Freeway on Saturday, Victoria Police said in a statement.

The woman told the officers that she had been traveling 80 kilometers per hour (50 miles per hour) when she felt something on her foot and looked down to find a tiger snake — one of the world’s most venomous serpents — slithering up her leg.

“Remarkably, she was able to fend the snake off her and weave through traffic before pulling over and leaping out of her car to safety,” the police said, adding that she was assessed by paramedics to ensure she hadn’t been bitten.
