What is the difference between a Breathalyzer and a field sobriety test?

A Breathalyzer and a field sobriety test are two different types of tests used in Texas to determine whether someone is under the influence of alcohol or drugs. A Breathalyzer is a device that measures the amount of alcohol in someone’s breath. It is usually administered by a police officer at the scene of a traffic stop. If the results of the test are above the legal limit, the person can be arrested for driving under the influence (DUI). A field sobriety test is a physical test performed by a law enforcement officer at the scene of a traffic stop. The purpose of the test is to determine whether someone is impaired by alcohol or drugs. It involves the officer asking the driver to perform a series of tests, such as walking in a straight line or touching their nose with their finger. If the officer believes the driver is impaired, the driver can be arrested for DUI. The main difference between a Breathalyzer and a field sobriety test is that the results of a Breathalyzer test directly measure the amount of alcohol in someone’s system, while a field sobriety test assesses physical coordination and ability to follow instructions. A Breathalyzer result is used as evidence in court, while a field sobriety test is just used by the police officer at the time of the traffic stop.
