Parent Bo Thompson has two kids going to Campbell Elementary School this year. He says he knew that speeding was a problem near the school before KTVA showed up on Tuesday to check it out.

"They don't pay attention to the speed limit," Thompson said about drivers in a school zone at Arctic and West 74th Avenue.

A viewer on Facebook asked KTVA to take a look at speeders near the school. With a speed gun in hand, on Tuesday, when school let out, we clocked a couple drivers going 39 mph in the 20 mph school zone.

One man was seen speeding and talking on his cell phone. Even a taxi was clocked going 34 mph.

"There are times that I have trouble crossing the road because they're speeding," said Russell Watkins who lives near Campbell Elementary.

While interviewing Watkins on camera, KTVA clocked a car going 39 mph.

"Too darn fast," Watkins said.

We stayed on scene about 50 minutes and saw driver after driver speeding. But many drivers were obeying the posted school zone speed limit, including a person in a student driver car. They were going 17 mph. A school bus and People Mover bus were also under the 20 mph speed limit.

KTVA is in contact with the Anchorage Police Department about what was seen on Arctic. On Wednesday, an APD spokesperson said they are working to set up an interview with someone from the traffic unit.

KTVA has clocked speeders at other Anchorage locations, including Romig Middle School. Last fall, APD invited us to tag along on a school zone speeding crackdown. Officers cited a number of speeders at Romig, and 31 people in all, that day, in Anchorage and Eagle River.

Police say it's important to send a message to drivers about slowing down around schools and children.
