In Eureka, Missouri, it’s not quite sundress and sandals weather, but it didn’t stop a 71-year-old C5 Corvette owner from running her errands in flip flops. When she was making a right turn to head into a store’s parking lot, her Corvette suddenly lost control. She said it felt like it “got a mind of its own.”

Seemingly out of nowhere, her 2003 Corvette hopped the curb and slammed into an unoccupied brick building. She was able to climb out of the car when paramedics arrived, but her Corvetter wasn’t so lucky.

“When we talked to her, she said she didn’t know what happened, her car just took off,” Police Captain Micahel Werges told Leader Publications, a local outlet.

Authorities discovered the source of the crash right away

Police and emergency personnel ruled out any drugs or alcohol, but they did notice something funny about her choice in footwear.

“When she was being checked by paramedics, officers looked in the car,” he recalled. “[The paramedics] noticed she didn’t have her shoe on. Her flip-flop was stuck, wedged under the pedal. We’re not exactly sure how that all happened, but it was very quick.”

Aside from the garaged ‘Vette, no one else was injured. The driver was taken to the hospital, but sustained only minor injuries.

Werges was happy to see everyone walk away from the crash, especially since it was close to commute time.

“Luckily, there were no severe injuries,” he said. “Central (Avenue) is right there, and that’s a really busy time of day.”

Sandals aren’t illegal, but they’re not smart

Several law firms are quick to point out that there’s no law in any state prohibiting flip flops while driving. Linda Iannelli, a traffic lawyer in California, often wears them herself while she drives—but you can still be on the hook if investigators can prove they’re the cause of a crash.

“Though there aren’t any laws, I would say there could be a liability angle if someone were in an accident and lawyers were somehow able to prove that the flip-flops caused the accident,” she told The U.S. Sun.

“Like if one of the flip-flops came off and got caught in the pedals and caused you to hit the gas instead of the brake. But it would be very hard to prove that was the case.”

Obviously, sandals with a back strap are much safer than those without—just be careful if sandals are loose fitting.
