How do 'depressant' drugs primarily affect driving?

• A. They speed up reactions
• B. They increase alertness
• C. They slow communication between the body and brain.
• D. They sharpen vision

Answer: (C)

Depressant drugs dampen the activity of the central nervous system, slowing the transmission of signals between the brain and the rest of the body. Driving hinges on quick processing of information, fast reactions, and precise coordination. When communication between the brain and muscles is slowed, reaction times lengthen, attention and concentration drop, and motor skills become less reliable. This makes it harder to respond to hazards, maintain lane position, and judge speeds and distances. These drugs do the opposite of sharpening or speeding up function, so they don’t increase alertness, improve reaction speed, or enhance vision. Instead, they reduce those abilities, which is why driving becomes significantly riskier under their influence.
