Two people -- caught in a traffic snarl caused by a collision between two tractor-trailers -- were in an accident themselves Wednesday night in Southern Illinois.

Christopher A. Masters, 20, of Cape Girardeau was cited for failure to reduce speed to avoid an accident in the incident, which occurred at Route 146 and Morgan School Road, four miles west of Jonesboro.

Masters' vehicle struck the passenger car driven by Deborah J. Poole, 31, of Jonesboro as Poole waited in a line of traffic caused by the previous wreck.

Masters was not injured. Poole sustained minor injuries and was transported to Union County Hospital. The accident occurred at 8:45 p.m.

The accident that caused the backup occurred at 8:42 p.m. when a tractor-trailer driven by James N. Robinson, 30, of Kingsburg, Ill., struck a tractor-trailer driven by David D. Wright, 36, of Jonesboro as Wright was backing his vehicle into a private drive at the intersection of Route 146 and Morgan School Road.

Robinson's tractor-trailer ran off the roadway and struck an embankment. Robinson sustained major injuries and was transported to Union County Hospital.

Wright was cited for improper backing on a roadway.

In an unrelated accident Wednesday evening at Mounds, a woman was cited for driving under the influence, illegal transport of alcohol, driving without insurance, driving without a seatbelt and disobeying a stop sign after she struck another vehicle at the intersection of U.S. 51 and Highway 37.

Carole K. Everett, 36, of Ullin was cited in the accident, which occurred at 5:30 p.m.

She was southbound on U.S. 57 at a "Y" intersection and ran a stop sign onto Highway 37, striking a vehicle driven by Neal Dover, 37, of Mound City, according to Illinois State Police.

Dover suffered major injuries and was transported to Southeast Missouri Hospital in Cape Girardeau.
