A woman was either trying to kill herself or was testing her ability to dodge moving vehicles on a Valley highway this morning. Either way, she failed -- she was hit by a tractor-trailer and lived.

According to the Arizona Department of Public Safety, the woman pulled her car to the side of I-17 near the Carefree Highway just before 7:30 a.m. today. She got out of the car and darted in front of an oncoming tractor-trailer.

The semi hit the woman, knocking her to the ground.

Meanwhile, DPS spokesman Robert Bailey tells New Times, an off-duty police officer was driving by and saw what happened. The cop tried to help the woman, but she wasn't having it.

As the officer tried to get the woman off the ground and away from the road, she jumped to her feet and ran into oncoming traffic -- again. The vehicles, luckily, managed to avoid hitting her.

The woman then walked to the center lane of the highway and laid down -- in front of another oncoming truck, which managed to stop before plowing over the her.

Bailey says the woman suffered several broken bones, but is in non-life-threatening condition and is expected to live.
