Question

1. which of the following is/are true?

○ a. we should not drive if we have any alcohol in our system, even small amounts.
○ b. most crashes occur when drivers are completely sober.
● c. even small amounts of alcohol decrease driver judgment and skill, and this increases the likelihood of crashing.
○ d. all of the above

Explanation:

• Option a: While any alcohol can affect driving, some regions allow driving with a very low BAC (blood alcohol concentration), so this statement is not universally true.
• Option b: Most crashes are associated with impaired driving (including alcohol - related), not when drivers are completely sober, so this is false.
• Option c: Alcohol, even in small amounts, impairs cognitive and motor skills related to driving, increasing crash risk. This is a well - established fact in traffic safety and the effects of alcohol on the body.
• Option d: Since a and b are false, d is also false.

Answer:

c. Even small amounts of alcohol decrease driver judgment and skill, and this increases the likelihood of crashing.
