Who may experience difficulty performing the Walk and Turn test?

The Walk and Turn test is a standardized field sobriety test that requires the individual to walk a straight line heel-to-toe and then turn on one foot before returning on the line. This test assesses balance, coordination, and the ability to follow instructions.

Drivers who have back, leg, or inner ear problems may have physical limitations that affect their balance and motor skills. For example, inner ear issues can significantly influence equilibrium, making it challenging to perform tasks that require stability. Similarly, injuries or conditions affecting the legs or back could lead to difficulties in maintaining proper posture and executing the walking pattern required during the test. These physical impairments can produce results that might falsely suggest impairment due to alcohol, thereby making it critical for law enforcement to consider such factors when interpreting the results of the Walk and Turn test.

While inexperienced drivers, those with mental impairments, or individuals who feel nervous might similarly struggle with the test, the physical aspects of balance and coordination are more directly impacted by musculoskeletal or vestibular issues, making that the most relevant reason among the choices provided.
