Question

the higher a drivers bac:

(select all that apply)

• the greater the likelihood is that the driver will have been at fault in the crash if one occurs
• the safer they are as a driver
• the greater the likelihood is that any resulting crash will be severe
• the more likely it is that the driver will crash

Explanation:

🆕 New Concept Discovered: Effects of Blood Alcohol Concentration (BAC)
How alcohol levels impair driving abilities and increase risks.

Step 1: Understand BAC and its effects

Blood Alcohol Concentration (BAC) measures the percentage of alcohol in a person's bloodstream. As BAC rises, central nervous system function decreases. This leads to impaired coordination, slower reaction times, reduced concentration, and compromised judgment.

Step 2: Evaluate each option

• "the greater the likelihood is that the driver will have been at fault in the crash if one occurs": Correct. Because alcohol severely impairs judgment and motor skills, an intoxicated driver is much more likely to make critical errors that cause an accident.
• "the safer they are as a driver": Incorrect. Higher BAC levels make driving significantly more dangerous, not safer.
• "the greater the likelihood is that any resulting crash will be severe": Correct. High BAC often leads to high-risk behaviors (such as speeding or failing to brake), which increases the force and severity of a collision.
• "the more likely it is that the driver will crash": Correct. Impaired reaction times and vision directly increase the probability of losing control of the vehicle.

Answer:

• the greater the likelihood is that the driver will have been at fault in the crash if one occurs
• the greater the likelihood is that any resulting crash will be severe
• the more likely it is that the driver will crash
