Which of the following is an effect of alcohol on driving ability?

Decreased awareness of surroundings is a significant effect of alcohol on driving ability. When a person consumes alcohol, it impairs cognitive functions and reduces the brain's ability to process information accurately. This diminished awareness means that a driver may not notice important visual cues on the road, such as traffic signals, pedestrians, or other vehicles, leading to a higher risk of accidents.

In general, alcohol affects several functions necessary for safe driving, including judgment, perception, and coordination. This impairment can make it challenging for drivers to respond appropriately to unexpected situations, further underscoring the risk associated with driving under the influence. Enhanced decision-making skills, increased concentration, and improved reaction time are all misconceptions about the effects of alcohol on driving; in reality, alcohol detracts from these critical driving functions, adversely affecting overall safety on the road.
