KATE GOSSELIN’s reckless driving could be endanger­ing the lives of her children.

That’s what friends are saying after the “Kate Plus 8” star was cited for several traffic offenses – includeing driving at 88 mph in a 65 mph zone in August.

“Kate’s hell on wheels,” declared an insider. “She’s had FOUR different traffic violations in the past two years.”

On Feb. 26, 2010,she was clocked going 73 mph in a 55 mph zone. And on Oct. 30, 2009, the 36-year-old was reportedly doing 70 mph in a 50 mph zone – with her eight chil­dren in the car!

“Lead-foot Kate has become even more of a speed demon since she started driving a $50,000 Audi sports car,” charged the in­sider.

“More times than not, she talks herself out of the ticket with an excuse. But the most upsetting part of her erratic driving is that she goes over the speed limit when the kids are in the car. It’s got friends and family scared to death.”

In the incident where she was caught going 88 mph, Kate explained to pals she was racing home from a business meeting at 1:37 a.m. to be with her kids.

Even though the children weren’t with her in the car that time, her ex-husband Jon Gosselin remains on edge.

“He fears for his kids when they ride with Kate and has lectured her about speeding,” said the insider. “But she considers it just part of being a harried mother of eight and doesn’t see it as putting lives at risk.”

With Kate’s nerves frazzled over the recent cancellation of her TV show – that could make matters even worse.

Warned the insider: “Those closest to her fear that in her current troubled state, Kate’s driving will get even more out of control.”
