A dangerous week for bicyclists on Kansas roads leads to a warning from police.

A 39-year old man is dead following a bicycle vs. car crash in Derby, and a 28-year-old remains in the hospital after a similar crash in Reno County.

A teenager was also struck by a car while on his bike in Hutchinson. He walked away with only minor injuries.

Now Reno County Sheriff Randy Henderson is urging drivers to be aware of their surroundings.

"It's a tragic event any time you have someone injured like this," said Henderson.

Henderson says Old K61 Highway in Reno County doesn't see a lot of traffic. The rural road has a small shoulder, which he calls a bike lane. But Henderson says that wasn't enough to prevent a crash involving a bicycle and a truck Sunday afternoon.

Henderson says 28-year-old Brett Brillhart was on his bicycle heading north when he was struck by the side mirror of a pick up truck, throwing him into the ditch.

"You feel for the bicyclist, you feel for the driver of the vehicle. There was no intention of this happening whatsoever," said Henderson.

This is the third time a bicyclist has been hit by a vehicle in south central Kansas in less than a week. Two crashes happened in Reno County, one in Sedgwick.

A crash involving a 15-year-old boy in Hutchinson was caught on a surveillance camera by Sunset Pawn near 4th and Main.

"It's a really busy intersection. We have at least one fender bender a month out there," said Chris deWit, Sunset Pawn Manager.

The boy was able to get back on his bike and ride away. The video shows the vehicle pulling over, but the boy was gone before the driver got out of the vehicle.

Four days later in Derby, another accident on S. Rock Road near 95th. 39-year-old Steven Lewis died after his bicycle was hit by a pick up truck. The driver of the truck said he never saw the bicyclist.

"They're difficult to see," said Henderson. "They sneak up on you or you may pull out in front of them. Just use more caution."

Kansas State Law requires drivers be at least three feet away from bicyclists while passing them. The Kansas Drivers Handbook recommends a distance of four feet.
