The Arizona Department of Public Safety (DPS) investigated two collisions involving five fatalities over the Thanksgiving holiday.
One fatal collision occurred in the Phoenix-metro area when a motorcycle crashed on a highway transition ramp, killing both riders.
The second fatal crash occurred on Interstate 40 near milepost 91. Investigators believe the crash occurred due to driver fatigue. Of the four people in the vehicle, two adults and one infant died as a result. Neither adult was wearing a seatbelt, and the 8-month-old infant was not in the child's seat. The driver was properly restrained and survived.
During Nov. 27 through Dec. 1 Highway Patrol units focused on increasing their presence along Arizona's highways. The main focus for the Highway Patrol was to deter unsafe driving by enforcing violations related to seatbelt usage, speed, impairment and overall dangerous driving behaviors.
Statewide, the Highway Patrol investigated 98 injury collisions and 212 non-injury collisions during the same time period.
Along the I-17 safety corridor, four non-injury collisions and one injury collision were investigated. In 2012, during the same period, five non-injury and one injury collisions occurred.
