What is one of the Phase One tasks in the Standardized Field Sobriety Test?

One of the Phase One tasks in the Standardized Field Sobriety Test (SFST) involves observing the vehicle in operation. This phase is crucial for law enforcement officers as it helps them identify signs of impairment before engaging with the driver. By observing the way the vehicle is being operated, officers can look for erratic behavior such as swerving, inconsistent speed, or other unsafe driving patterns that could indicate that the driver is under the influence of alcohol or drugs.

This preliminary observation sets the foundation for further evaluation during the SFST process. Additionally, the other options, such as noting the time of day, weather conditions, or assessing the driver's blood type, do not directly pertain to the immediate assessment of the driver's state while behind the wheel, which is the focus during Phase One.
