However, these situations might be challenging to prosecute since officers sometimes have trouble spotting the symptoms of such impairment. Nevertheless, depending on the type of substance they were using at the time, anyone charged may also be prosecuted for drug possession.

A Typical Investigation into Drunk Driving

According to the National Highway Traffic Safety Administration, 30 persons per day pass away in incidents involving drunk drivers. This shocking number is one of the many reasons why law enforcement organizations work tirelessly to remove drunk drivers from the road. Even if different jurisdictions may have their own methods for investigating drunk driving, there are certain common aspects.

The First Stop

There are specific procedures that an officer must follow before filing charges when they have reason to believe that a driver is operating a vehicle while under the influence of alcohol or drugs. 

First, there needs to be a valid justification for the traffic stop. Before making a traffic stop, the officer must see the driver disobeying the law. 

Here are a few typical instances of common traffic infractions:

  • Speeding
  • Failure to keep the traffic lane clear
  • Disregarding traffic control measures

In addition, the officer might notice another issue with the car, like a damaged taillight or a license plate that is obstructed. 

The investigation into impairment starts when an officer pulls over a vehicle. The policeman takes note of any alcohol odor coming from the driver or the car. The eyes of a driver may also reveal indicators of intoxication to the police. These observations strengthen the DWI case.

The Breathalyzer Test

An officer may employ numerous strategies to support a reasonable suspicion that a driver is intoxicated when they believe it to be true. A breathalyzer is the most typical test to determine how much alcohol is in a suspect’s system. Drivers who refuse to submit to a breath test often lose their driving privileges for a set amount of time. The agreement to submit to a breathalyzer or blood test upon a police officer’s request is one prerequisite for obtaining a license. If refused, the motorist must give up their driver’s license.

Field Sobriety Tests

Police require drivers to complete a series of easy physical tasks known as field sobriety tests while on the scene. Among the tests are balance, the capacity for following instructions, and other fine motor skills. The most often used tests are the heel-to-toe walk, single-leg balance, and nystagmus gazing.
