Question

what is a risk that causes many teen car crashes?
driving cars with poor safety ratings
listening to loud music
driving under the influence
wearing sunglasses that impair vision

Explanation:

To determine the risk causing many teen car crashes, we analyze each option:

• "Driving cars with poor safety ratings" is less common as a primary cause for teens (many teens drive family cars with standard ratings).
• "Listening to loud music" is a distraction but less impactful than impaired driving.
• "Driving under the influence" (of alcohol/drugs) severely impairs judgment, reaction time, and motor skills, a well - documented major cause of teen car crashes.
• "Wearing sunglasses that impair vision" is a minor or rare factor.

Answer:

C. driving under the influence
