Three new speed cameras go online in Dayton Wednesday.
Two cameras are located at Gettysburg Avenue at Fairbanks Avenue. The other is at North Main Street at Siebenthaler Avenue.
Both locations will begin a 30-day warning period on Wednesday.
A mobile speed trailer has also been placed on North Main Street near Forest Glen Avenue, adding to two mobile cameras already operating in Dayton. It will also be activated on Wednesday, with no warning period.
During the 30-day warning period for the new fixed camera sites, the registered owner of the vehicle caught violating the speed limit will receive a warning in the mail.
After 30 days, citations will be issued by mail and will include payment and appeal directions.
Dayton Police Department data shows injury crashes are down in Dayton about 15 percent from January 1 to April 9, 2018, compared to the same period in 2017.
Violations are also down in current photo enforcement sites.
Preparations are underway at two sites which will eventually have red light enforcement cameras. Those locations are Linden Avenue at Smithville Road and West Third Street at James H. McGee Boulevard.
