A Dunn County Sheriff's Deputy utilizes a Laser unit along STH 25 enforcing speed.

Speed Enforcement The Sheriff's Office is well equipped and very progressive when it comes to traffic and speed enforcement. All squads are equipped with radar systems. These systems allow patrol vehicles to monitor vehicle speeds of targets that are in range of the patrol vehicle. The unit can monitor vehicles ahead or behind the patrol vehicle, and moving away from or closing in on the patrol vehicle. The unit can also monitor two separate target vehicles at once, for use on divided highways or roadways with heavy traffic. Deputies   also   use   handheld   Laser   enforcement

devices, also known as lidar. Laser allows deputies to pinpoint target vehicles and obtain vehicle speeds instantly, even in heavy traffic or multiple lanes of traffic. Laser enforcement is basically fool-proof, and an exact speed reading will be obtained within seconds of activation. Laser also uses a very slim "beam of light" used to obtain target vehicle speeds. This makes 'radar detectors', or 'fuzz busters' useless. Detectors will not pickup laser units ahead on the highway because the light emitting from the laser unit is so narrow and directed only at the target. If a laser unit hits your vehicle with a detector, the laser will already have a speed locked by the time your detector goes off. If you know of a speed problem in your neighborhood, you can request extra patrol from patrol deputies by calling 715-232-1348.

OMVWI & Impaired Driving Dunn County deputies strictly enforce the OMVWI laws of Wisconsin. Impaired drivers across the country endanger the lives of other citizens on the roadway every day. In 2008, officers arrested more than 42,000 drunk drivers from Wisconsin roads, but drunk driving fatalities still were up from 2007. In 2006, more than 15,000 people were killed in the U.S. from drunk driving related crashes. If you see a possible drunk driver on the highways, call 9-1-1- immediately.

Crash Reconstruction
The Dunn County Sheriff's Office has two deputies that have received specialized training in crash investigation and reconstruction. Vehicular accident reconstruction is the scientific process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists are employed to conduct in-depth collision analysis and reconstruction to identify the collision causation and contributing factors in different types of collisions, including the role of the driver(s), vehicle(s), roadway and the environment. The laws of physics and engineering principles such as the conservation of linear momentum, work-energy methods, and kinematics are the basis for these analysis and may make use of software to calculate useful quantities. The accident reconstruction provides rigorous analysis that an expert witness can present at trial. Accident reconstructions are done in cases involving fatalities, and often when personal injury is involved. Results from accident reconstructions are also useful in developing recommendations for making roads and highways safer, as well as improving safety aspects of motor vehicle designs.

DRE (Drug Recognition Expert) Program

A drug recognition expert or drug recognition evaluator (DRE) is a police officer trained to recognize impairment in drivers under the influence of drugs other than, or in addition to, alcohol. The International Association of Chiefs of Police (IACP) coordinates the International Drug Evaluation and Classification (DEC) Program with support from the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation.

DRE also administers carefully designed psychophysical tests to evaluate the person’s judgment, information processing ability, coordination and various other characteristics. The DRE will systematically consider everything about the person that could indicate the influence of drugs.

DREs generally deal with cases relating to persons that are suspected of driving under the influence of drugs but also may assist on any criminal case where it may be necessary to determine if there is drug impairment. DREs also may be used when responding to certain medical calls and are proven useful to determine if illicit or prescription drug abuse is related to the medical problem. They can often times provide valuable information to responding medical professionals to help the patient. DREs also are a community resource to school liason officers, school officials, and parents if an issue arises where a student may be suspected of using drugs.
