**Alcohol** is a substance that negatively affects the body, especially the **brain** and **vision**, which can lead to **traffic accidents**. When a person consumes alcohol, their ability to assess their own **effects** diminishes, which means that, as a general rule, they **do not adequately assess** how alcohol is affecting their ability to drive.

Additionally, the laws are strict regarding alcohol consumption at the wheel. Driving under the influence of alcohol is **prohibited** and can result in **fines** or even **imprisonment**. This reinforces the idea that people who have consumed alcohol are not fully aware of its effects, as if they were, they would avoid driving to not face these legal consequences.

Therefore, the statement that the driver who has consumed alcohol **does not assess its effects, as a general rule**, is correct.
