What should be checked to ensure an operator's capability to perform sobriety tests?

Ensuring an operator's capability to perform sobriety tests involves evaluating their physical ability to conduct the tests effectively. Conducting sobriety tests requires certain physical skills, including balance, coordination, and the ability to observe and interpret behaviors accurately. Assessing for physical disabilities helps confirm that the operator can perform these tasks without any limitations that could affect the results of the sobriety testing.

Checking the vehicle registration, driver's insurance status, or time-elapsed assessments does not address the specific requirement for a field sobriety test operator. These factors are important in a broader context of traffic enforcement and safety but do not directly pertain to the operator's physical capability to conduct sobriety tests accurately and effectively. Understanding the operator's limitations ensures that the sobriety tests are administered fairly and yield reliable results.
