Question

Difficulty: EasyPhysiological Effects of Alcohol on Driving Performance

Consuming alcohol degrades a driver's divided attention ability, making it significantly harder to monitor speed while simultaneously scanning for potential road hazards.

Answer: Answer

Answer

True. Alcohol depresses central nervous system functions required for divided attention, impairing a driver's ability to process multiple driving tasks simultaneously.
Alcohol is a central nervous system depressant that degrades divided attention—the cognitive ability to process multiple sources of visual and spatial information simultaneously. As a result, drivers under the influence struggle to manage simultaneous driving tasks such as maintaining lane alignment while scanning for hazards.

Step-by-Step Solution

1
Analyze how alcohol affects cognitive processing and multi-tasking skills required for driving.
Alcohol depresses central nervous system function, which reduces the brain's information-processing capacity.
Safe driving requires constantly dividing attention between steering control, speed monitoring, and hazard detection.
2
Evaluate the truth value of the statement regarding divided attention degradation.
The statement is accurate because divided attention is impaired even at low blood alcohol concentrations.
A driver under the influence will struggle to focus on critical secondary tasks like instrument monitoring while maintaining visual scanning of the roadway.
