The Arizona Department of Public Safety released some of its statistics from its zero-tolerance initiative that began in November.

Troopers were out on eight separate details starting on Nov. 10, 2017, in order to crack down on speeding drivers along Valley freeways. DPS focused mainly on the Loop 101, 202 and 303.

While troopers were enforcing speed limits throughout the month of November, the eight days reflected in the released statistics are the only days DPS ran actual details in which the department enhanced staffing by pulling from other districts around the Valley.

In all, DPS stopped 221 drivers and cited 174 of them. Troopers gave warnings to 47 drivers and arrested two individuals.

DPS did not release any information regarding the arrests.

Troopers working these details were also required to respond to calls for service.

The times were selected as peak traffic hours and when most collision occur. Additionally, DPS said some of the times were used after or before peak hours to enhance enforcement outside of the peak hours.

Two of the details occurred around Thanksgiving holiday. On Nov. 22, DPS made 28 stops, citing 24 drivers and warning four.

On Nov. 24, troopers stopped 32 drivers, citing 29 of them and warning three.

The two arrests occurred in the first two segments, one each on Nov. 8 and Nov. 10.

A DPS official said there are discussion about where and when to have the next zero-tolerance speeding campaign.
