More than 300 drivers who received red light and speed camera tickets in Longview will catch a break because the tickets said the violations occurred in Lynnwood.

Both cities contract with American Traffic Solutions, an Arizona-based company that provides the equipment and helps manage the system. A city of Longview spokesperson said the mistake was the result of a computer coding error.

“As part of the normal review and quality check process performed by ATS, it was discovered that an improper computer code caused the city of occurrence to be listed as Lynnwood when the traffic violation occurred in Longview.  As a result, 303 notices of infraction issued from February 14 through March 8, 2011 will be dismissed,” Longview spokesperson Susie Myers said.

Refunds will be issued to drivers who already paid their tickets. The others will be automatically dismissed.

Longview’s automated traffic safety cameras started operating one month ago.
