22.00.100 TRAFFIC ENFORCEMENT VEHICLES (CALEA 61.1.6)
Vehicles used by the Department for traffic enforcement will be distinctively marked and equipped with emergency lights and siren. The Traffic Unit Commander may authorize the use of an unmarked vehicle for enforcement when appropriate.
While on patrol, officers will operate vehicles in accordance with existing laws and in such a manner as to demonstrate exemplary driving behavior.
In areas where fixed-post observation is necessary to maximize the effectiveness of enforcement efforts, officers will park in a safe and conspicuous location and in such a manner that traffic and pedestrian flow is not impeded.
Off-road observations are permitted, however, every effort should be made to remain visible and avoid the appearance of a "speed trap".
The Department does not utilize roadside safety checks as part of its traffic enforcement program.
Emergency Equipment (CALEA 41.2.1)
The proper use of emergency equipment is essential to the safety of the officer, motorists and pedestrians. Officers will use emergency equipment in accordance with State law and existing Department policy in the following situations:
v Vehicular pursuits
v Response to an emergency
v Response to a crime in progress
v Pursuing and stopping violators
v Motorist assistance
v Parking (on/off the roadway) when hazardous conditions exist
Officers, unless directed otherwise by State law or Department policy will exercise discretion in the use of emergency equipment. This discretion will be based on the following:
v Emergency (Red/Blue) Lights
This equipment, used in conjunction with other equipment, signals a vehicle to stop or signals other users of the roadway that emergency conditions exist and the right-of-way should be relinquished to the enforcement vehicle.
Officers should not assume that lights and/or siren will be sufficient to assure the right-of-way and are obligated to drive with due regard for the safety of all persons using the street.
Once the emergency ceases to exist or both the enforcement vehicle and violator vehicle are safely parked off the roadway, emergency lights may be extinguished at the officer's discretion.
Hazardous warning lights, including 4-way flashers and the flashing headlight system should be used in conjunction with other emergency equipment and as circumstances dictate.
Spotlights are used for the protection of the officer during traffic or criminal stops at night. The spotlight may be used to illuminate the interior of the violator's vehicle so all occupants are kept within view. Officers should not use the spotlight to signal violators to stop and should not illuminate the interior of the vehicle until it has stopped, or nearly stopped.
Emergency vehicle high beam headlights, spotlights, alley lights, hazardous warning lights, and other emergency equipment can all be used to the officers’ advantage on traffic stops, motorist assists, traffic accidents, and area searches. Officer discretion should be used when positioning lights and vehicles to avoid unnecessary interference with homes, businesses, and vehicle traffic while maximizing protection for the officer and persons contacted. Whenever possible, vehicles shall be parked off the traveled portion of the roadway to reduce the potential for collisions.
v Other Equipment
Sirens are to be used as needed and in conjunction with emergency lights and in accordance with applicable state law.
Public address system may be used when the officer determines it is necessary to audibly direct persons, such as in high risk stops, in alerting pedestrians to hazards and in relieving emergency conditions.
