Question 556

What effects does a cell phone conversation lasting more than a minute and a half have on driving?

  1. The driver does not fail to notice signs if using a hands-free device.
  2. Average speed increases, even with a hands-free device.
  3. The driver fails to notice a significant proportion of the signs, even with a hands-free device.
Show answer and explanation

Correct answer: The driver fails to notice a significant proportion of the signs, even with a hands-free device.

After more than a minute and a half of conversation, a driver may stop noticing a significant proportion of traffic signs. A hands-free device does not eliminate this distraction.
