POCATELLO, Idaho (AP) — The director of the Idaho State Police has rescinded permission for the use of red lights on security vehicles at Idaho State University.

Col. Ralph Powell in a letter obtained by the Idaho State Journal (http://bit.ly/1Ae0Fk1 ) and cited in a story on Monday orders the suspension of the use of red lights on campus patrol vehicles.

Idaho State University President for University Advancement Kent Tingey says the school will comply.

Powell in the letter to Idaho State University Public Safety Director Steve Chatterton dated Dec. 17 cites information that campus security has been using the red lights to stop motorists.

The school said it obtained permission in 1996 from a former Idaho State Police director.

But Powell says the red lights are limited to alert traffic, not conduct traffic stops.
