Video of the purported incident surfaced Monday, showing a woman identified as de la Huerta, 31, being struck by an ambulance and thrown to the ground.
The clip was reportedly shot during the filming of Nurse 3D in October 2011 and is being used a evidence in a $55 million breach-of-contact lawsuit filed by the actress against Lionsgate, reports the New York Daily News.

According to the paper, de la Huerta suffered a broken tailbone and spinal fracture in the accident and was forced to put her career on hold to undergo more than 20 surgeries to help correct her injuries.
In court documents obtained by PEOPLE, de la Huerta also claims, in addition to the on-set injury, a breach of contract by Lionsgate for using an unauthorized voice-over for her character.
The actress states that producers approached her to record sound bites for the film, which she alleges she did, but that Lionsgate had the voice "redone" using a "Jane Doe" recording from another performer. The actress claims she did not learn that her performance had been dubbed over until the film was released, and that the poor quality of the voice-over damaged her career.
"As you can see in the video, what happened that night was terrible. It has scarred me both physically and emotionally for many years," the actress previously told the Daily News.

The film studio requested the hearing on Tuesday in hopes of dismissing the case, but the judge denied the request and ruled to allow the lawsuit to proceed.
A spokesperson for Lionsgate declined to comment.
"We're moving forward, which is great," she told the Daily News following the hearing. "So I really do hope that justice prevails."
Although de la Huerta was awarded workers' compensation following the accident, she claims she spent all her "life earnings" on her medical care.
"Living in pain wasn't an option and I didn't have any familial support, so I spent all my life earnings on my surgeries and everything, and it's time for them to pay," she said.
