Final answer:
Impaired driving can be caused by several factors including drinking alcohol, taking illegal drugs, and taking prescribed drugs, either separately or combined. All of these substances can affect motor skills, judgment, and reaction times, making driving dangerous.
Step-by-step explanation:
Impaired driving can be caused by drinking alcohol, taking illegal drugs, taking prescribed drugs, or all of the above. Drinking alcohol leads to decreased coordination, blurred vision, and impaired judgment, which can greatly increase the risk of road accidents. Alcohol is a depressant, and at higher doses, it can cause severe side effects like slurred speech, trouble walking, and even coma or death in extreme cases. Similarly, both illegal drugs and prescribed medications can cause impairment, especially when taken in high doses, leading to overdoses and impairments that are dangerous while driving. It's important to recognize the risks associated with these substances and understand that they can all contribute to impaired driving.
