Their son's school bus stop is on a U.S. highway so a Mound City family wants signs posted to warn drivers of what's ahead. The parents say it's a safety issue, but the state says it's not necessary.

Mound City doesn't have a lot of people, but Highway 83 runs through it and does see a fair amount of traffic.

That's why before Bernie and Susan Baker's son gets on the bus one more time, they want a warning sign posted up the road from where it stops on the highway.

"At least on the north end of town coming over the hill,” Bernie Baker said. “Let them know there is a farm on this side, there is a house, there is children and could they please just slow down a little bit.  It is a school bus stop now that the school year's coming up again."

The state has looked into putting a sign there warning people that there is a school bus stop ahead. And it has its reasons for deciding against it.

The Department of Transportation will put up a sign if drivers can't see the stopped bus within a certain distance. The Bakers live in a 45 mile an hour zone and DOT's standard distance at that speed is 175 feet. The sight distance for the Baker's driveway is 750 feet.

"When they told me they could stop the trucks within the time distance, I offered to put a chair in the lane of traffic coming from the north and invited the governor to come down and sit in it," Baker said.

Baker hasn't had any takers on that offer but the DOT says the distance to his driveway is also more than enough for a 65 mile an hour zone.

But with a 10-year-old son getting on and off a bus as traffic comes over the hill near their home, the Bakers aren't convinced it's safe.

"It scares us. It really makes us nervous," Baker said.

The DOT says if it doesn't follow the standards, people could see signs where they're unnecessary and start ignoring them altogether.
