Police say they are very concerned over safety on Calgary highways after a number of drivers were caught driving over the speed limit on Deerfoot Trail.

Members of the Calgary Police Service Traffic Section conducted a targeted speed project over a three hour period in the area of the 6400 block of Deerfoot Trail N.E.

During that time, police say they stopped 51 drivers for breaking the limit, with 60 tickets issued.

Among the driver, police found the lowest speed was recorded at 120 km/h while the highest was 157 km/h. The speed limit in the area is posted at 100 km/h.

The CPS says that speed in that section of Deerfoot Trail is of great concern because of the risk to other drivers. Officers attending the crackdown also say that they also witnessed a number of close calls during the program.

Drivers are being reminded to obey speed limits, drive to road conditions, and always leave room to react in an emergency.
