What does a score of two or more clues indicate in the Walk-and-Turn test?

In the Walk-and-Turn test, a score of two or more clues is an indication of a likelihood of impairment. This field sobriety test is designed to assess a person's balance, coordination, and ability to follow instructions, which are skills impaired by alcohol or drugs.

When a subject exhibits two or more clues, it suggests that they may not be able to complete the test as an unimpaired individual would. Common clues include inability to maintain balance during the instruction phase, starting too soon, stopping while walking, or failing to touch heel-to-toe. Each of these indicators reflects a potential impairment in cognitive and motor functions, supporting the conclusion that a driver's abilities might be compromised. Therefore, a score reflecting multiple clues serves as a basis for the officer to suspect that the individual is under the influence, warranting further investigation or testing.
