LEE’S SUMMIT, Mo. — An off-duty driver examiner saw a woman driving erratically before crashing into a median. The woman’s blood sugar level got dangerously low when she was driving east bound on I-70 and caused her to crash.

Thanks to the Missouri State Highway Patrol, she’s still alive.

“My car stopped, I was in the median, I didn’t quite understand how I got there,” said Kristi Jenkins, who has type 1 diabetes.

“She was driving erratic from the shoulder over to the fast lane,” said Cindy Durbin, who witnessed the whole thing, “almost hit two concrete pillars and bridges!”

Jenkins was heading home from work Thursday when her blood sugar levels dropped.

“The next thing I knew there were paramedics by my car,” Jenkins said.

Durbin, an off-duty driver examiner for MSHP, happened to be driving behind Kristi and noticed something was wrong.

“I was scared for people that were trying to pass, I was scared for her,” said Durbin, who put her emergency blinkers on to alert other drivers.

Durbin was on the phone with the highway patrol for 15 minutes before Jenkins finally crashed into the median. Durbin pulled over to help.

“She could talk, but she was very distraught,” said Durbin. “Her being coherent was fading in and out.”

Jenkins’ blood sugar dropped to 29. Dr. Melissa Smith, with the Lee’s Summit Medical Center said Kristi is lucky she walked away without any injuries.

“Typically you’re looking for blood sugar over 60, that’s typically as low as your body will go without showing symptoms,” said Dr. Smith. “At 29, it would be very surprising that she is still functioning, still driving a car!”

Kristi said its unusual for her blood sugar to get that low.

“Sometimes with a dramatic drop like it did yesterday, it dropped way too fast for me to even recognize the symptoms,” said Jenkins, “I’m very grateful that nobody got hurt, that no one else was involved!”

Doctors and the highway patrol say driving with certain medical conditions is just as dangerous as driving under the influence. They hope everyone takes the necessary precautions before getting behind the wheel.
