Cars with the 6G## call sign belong to what used to be know as Freeway Patrol Units at Leduc, Ponoka, Innisfail, and Airdrie. Although they were in different subdivisions they all used 6 as they were commanded out of the Red Deer subdivision. They still use 6G## (except for Airdrie which switched a number of years ago to a Highway Patrol Unit using 2C##) They are all now called Traffic Services Units or where combined with the Sheriff's HP, Integrated Traffic Units.
