What does the process of explaining and demonstrating tests to the driver entail?

The process of explaining and demonstrating tests to the driver involves instructing the operator on how to perform field sobriety tests effectively. This step is critical because it ensures that the driver understands the nature of the tests being administered and what is required of them during the evaluation. By providing clear instructions and possibly a demonstration, the operator can enhance the driver's ability to comply with the test, thus contributing to the validity of the results.

This practice not only helps in obtaining accurate data regarding the driver’s sobriety but also protects the integrity of the testing process by making sure that the driver is not unfairly disadvantaged due to a lack of understanding. Proper instruction can lead to more reliable assessments of the driver’s capability to safely operate a vehicle.
