Which of the Following Processes is Used to Test For Drunk Driving?
When someone is arrested for drunk driving, the police will likely use one of the following processes to evaluate their ability to drive. A standardized field sobriety test is often portrayed on television programs like “Cops.” This procedure requires a suspect to walk along an imaginary line in a road from heel to toe, then turn abruptly after completing a certain number of steps.

Field sobriety tests
Field sobriety tests are often requested by police when a driver is suspected of drunk driving. They can help police determine whether a driver is impaired or intoxicated and provide probable cause to arrest the driver. However, they are not foolproof and can be prone to misinterpretation. In addition, officers often administer them under stressful conditions. For this reason, it is essential for police to use a reliable measurement tool in determining the level of impairment.
There are several different types of field sobriety tests. The most common are balance tests, eye tests, mental agility tests, and walk-and-turn tests. The walk-and-turn test requires the driver to walk in a line while keeping his or her eyes fixed on an object. The officer is looking for jerky eye movements or nystagmus.
Preliminary alcohol screening test (PAS)
A preliminary alcohol screening test (PAS) is a test that is used to test for drunk driving. This test is generally accurate, but it cannot be 100% accurate. If you are caught driving under the influence of alcohol, the PAS results will be used to determine whether or not you are guilty of DWI.
It is often confusing to distinguish the PAS test from the Breathalyzer, which is much larger and more precise. The PAS test is a simple, hand-held device that requires the suspect to breathe into a device. The device provides an instant BAC estimate, which the police officer can use to determine whether to arrest the suspect. However, it is important to remember that a positive PAS test does not automatically make the driver guilty of drunk driving and it is not admissible as evidence in many states.
Chemical breath test
The chemical breath test for drunk driving is an instrument used to determine a person’s blood alcohol concentration. Alcohol is absorbed into the bloodstream rapidly and reaches its peak concentration approximately one hour after drinking. Once it reaches the bloodstream, alcohol is quickly removed by the body through excretion, metabolism, and evaporation.
The test results of a chemical breath test are considered admissible in court. Unlike a blood test, a chemical breath test is a non-invasive process. Typically, a driver must stay in the police station for fifteen minutes and blow into a machine. It measures the amount of alcohol in one’s breath and the alcohol content in two or more samples. If the chemical breath test results are positive, the officer can arrest the driver. Refusing to take the test can result in a civil infraction, which carries no points and a $150 fine. Drivers with a commercial license must also be aware of the consequences of refusing.
Modified position of attention test
A modified position of attention test is a physical and mental task that police use to determine if someone is impaired by alcohol. The suspect is asked to stand on one leg, close their eyes, and tilt their head backward. This test can indicate if a driver has been drinking or taking drugs. The officer can use this information to make a DUI charge more probable.
The one-leg stand test is primarily a test of balance. A driver may be incapable of standing on one leg for a variety of reasons, including insufficient coordination. The modified position of attention test, also known as the Rhomberg test, consists of observing a driver standing on one leg with his or her eyes closed for 30 seconds. The test assesses the driver’s body tremors and swaying while balancing on one leg. In addition, it reveals how well a driver follows directions and perceives time.
