Final answer:
Yes, a driver can be convicted of driving under the influence if they are impaired by any substance, including but not limited to alcohol. These substances can cause many dangerous impairments, including reduced reaction time and cognitive function.
Step-by-step explanation:
The statement is true. In addition to alcohol, a driver who is impaired by legal (prescription and over-the-counter medications) or illegal drugs can indeed be convicted of driving under the influence. Impairment reduces a driver's reaction time, alertness, behavioral control, and other aspects of cognitive function, which can lead to dangerous situations on the road. Alcohol and other psychoactive drugs like depressants can cause a variety of changes to consciousness. At low doses, people might feel euphoric, while higher doses can lead to sedation and even a complete loss of consciousness. Ultimately, the use of such substances while driving is heavily punished in many jurisdictions to safeguard public safety.
