During the One Leg Stand test, what should the driver do after taking the first step?

The One Leg Stand test is a field sobriety test used to assess a driver's balance and ability to follow instructions under the influence of alcohol or drugs. After taking the first step, the driver is instructed to count out loud for a specific duration or number of counts while holding the raised leg. This counting helps the officer evaluate the driver’s mental acuity and physical coordination simultaneously.

Counting out loud demonstrates the individual's ability to follow directives and maintain concentration, which can be challenging for someone impaired by alcohol or substances. This requirement is crucial for assessing the driver's impairment level, as it demands both mental and physical engagement.

The other options would not align with the requirements of the test or the intent of demonstrating both physical coordination and cognitive function. For example, stopping movement would not fulfill the test's requirements for balance assessment, and asking for clarification might indicate confusion or lack of understanding, which is not desirable during this evaluation. Getting ready to turn does not pertain to the specific steps of the test. Therefore, the correct action after taking the first step is to count out loud.
