Final answer:
The statement is false; alcohol and certain drugs are both depressants that can impair driving, and law enforcement uses the Field Sobriety Test to assess impairment.
Step-by-step explanation:
The statement is False; alcohol and drugs can both impair driving. Both alcohol and other depressants, such as certain drugs, can have significant effects on the central nervous system. Ethanol, commonly known as alcohol, is a psychoactive substance classified as a depressant. When ingested, alcohol can cause changes in consciousness, including reduced reaction time, decreased visual acuity, lower levels of alertness, and impaired behavioral control. High doses can even lead to a complete loss of consciousness or blackouts. The Field Sobriety Test (FST) is often used by law enforcement to assess a driver's level of impairment by checking coordination and balance, which are dependent on the cerebellum, a brain region very sensitive to the effects of alcohol.
