The tiny municipality of Calverton Park in North St. Louis County is the site of a pair of new speed cameras.
The cameras are the first in the state to carry the blessing of the Missouri Department of Transportation.
A new media campaign in support of red light cameras rolls out across Missouri today.
The advertisements are sponsored by a group calling itself the "National Coalition for Safer Roads."
David Kelly is the executive director. He says there is a false impression that a majority of Missourians are opposed to red light cameras.
