What indicates a "pass" in the Walk-and-Turn test?

The Walk-and-Turn test is designed to evaluate a person's balance, coordination, and ability to follow instructions, which are key indicators of impairment. A "pass" is indicated by demonstrating good balance and properly following the test instructions without exhibiting any physical or behavioral clues that suggest impairment. This includes walking heel-to-toe in a straight line, accurately turning around as instructed, and returning to the starting position without losing balance or stumbling.

In this context, the ability to maintain appropriate balance and follow instructions closely reflects the individual's cognitive and physical faculties. If a person is able to perform these actions smoothly and as per the instructions given, it showcases their capability to navigate tasks that require focus and coordination, which are adversely affected by alcohol or drugs.

The other choices, while relevant to performance, do not solely encompass the criteria for a "pass" in the Walk-and-Turn test. For instance, simply walking without any signs of impairment may not consider the specific requirements of the test, such as the heel-to-toe walking and following the verbal instructions. Similarly, completing the test within a time frame does not directly correlate with demonstrating the necessary skills for a pass, and remaining silent does not impact the evaluation of physical ability or mental clarity during the test.
