What effect does driving under the influence of drugs have on commercial drivers?

Driving under the influence of drugs significantly impairs judgment, reaction times, and overall driving ability. This impairment can lead to poor decision-making on the road, such as misjudging distances and speeds, which are crucial for safe driving, especially for commercial vehicles that often carry larger loads and have different handling characteristics compared to standard vehicles.

Additionally, drugs can affect cognitive functions, making it difficult for a driver to concentrate or respond promptly to unexpected situations—an essential skill for commercial drivers who may encounter various road environments and hazards. This is particularly critical because commercial driving often involves greater responsibility, such as transporting passengers or hazardous materials, where safety is paramount.

The other options incorrectly suggest that driving under the influence of drugs either enhances driving skills, has no impact, or only affects physical driving skills. In reality, the combination of impaired judgment and slowed reaction times creates a hazardous situation for both the driver and others on the road.
