KUSA – A driver who dropped a large box with wires hanging out of it and drove off from an Aurora neighborhood Monday wasn't up to anything sinister.

Instead, he was taking part in a bus driver security training exercise for Cherry Creek Schools.

The incident in the Tollgate Crossing neighborhood alarmed one 9NEWS viewer who witnessed it.

Cherry Creek Schools Spokesperson Tustin Amole says it was part of a routine training for bus drivers intended to make sure drivers take action should they see something or someone suspicious while driving their route.

Security awareness is standard training for many area school districts' bus drivers of one kind or another.

Denver Public Schools trains all its drivers and paraprofessionals to check their bus and to be on the lookut for any suspicious items both before and after each run.

Jefferson County Schools offers video training for its drivers covering security awareness.

Douglas County Schools uses the Transportation Security Administration's School Transportation Security Awareness program in its driver training.
