PrepTest 88, Section 3, Question 23
Safety expert: Conversing on a cell phone while driving is more dangerous than conversing with a passenger in the vehicle. The person talking with the driver on a cell phone is unable to see the driving situation and, hence, cannot immediately recognize situations in which driving becomes difficult. In contrast, a passenger in the vehicle will usually be quiet or even provide helpful warnings in such situations.
