Which of the following tests is commonly used to detect impairment during DUI checkpoints?

The Walk and Turn Test is a standardized field sobriety test that law enforcement officers commonly use to assess a driver's level of impairment during DUI checkpoints. This test is designed to measure various physical and cognitive abilities, such as balance, coordination, and the ability to follow instructions.

During the test, the individual is asked to walk in a straight line, typically taking nine steps heel-to-toe, turn on one foot, and return in the same manner. Success on this test requires the individual to maintain balance while also listening and responding to directions, which can be particularly challenging for someone impaired by alcohol or drugs. Observations of how well a person can perform this test provide officers with valuable evidence of potential impairment.

The other tests mentioned, while they do assess different aspects of physical ability, are not as commonly used in the same context or may not provide as clear indicators of impairment as the Walk and Turn Test. This makes it the preferred choice during a DUI checkpoint evaluation.
