At what point should the driver maintain the heel-to-toe position in the Walk and Turn test?

The correct answer is that the driver should maintain the heel-to-toe position at all times during the Walk and Turn test. This test is designed to assess a driver's balance and coordination, which are crucial indicators of impairment. The heel-to-toe position helps establish a clear standard for how the test should be performed, allowing the officer to evaluate the driver's ability to follow directions and maintain stability throughout the entire sequence of the test.

Maintaining this position during both the walking and turning phases is essential because any deviation may suggest a lack of coordination. The driver is expected to start in the heel-to-toe position, walk a specified number of steps, turn, and return to the starting point without breaking the heel-to-toe alignment. This standardization is important for an accurate assessment of the test results.
