According to the illegal per se law, what is prohibited?

The illegal per se law specifically prohibits operating a vehicle while impaired to any degree, meaning that a driver can be charged with a DUI even if their blood alcohol concentration (BAC) is below the commonly recognized legal limit. This legal standard is designed to create a strict liability for impaired driving, emphasizing that any amount of impairment can affect driving ability and, therefore, public safety.

This law is established to deter individuals from consuming alcohol or other intoxicants before driving, regardless of their actual level of impairment in terms of their driving performance. It underscores the understanding that even minimal impairment can significantly increase the risk of accidents, making it a critical aspect of traffic laws aimed at preventing impaired driving incidents.

In contrast, the other options pertain to behaviors that, while violations, do not fall under the same strict liability standard established by the illegal per se law. For instance, operating a vehicle while fatigued or without a license and operating without insurance involves different legal considerations and requirements that may allow for defenses or differing degrees of culpability compared to the absolute prohibition represented by the illegal per se law.
