Final answer:
The statement citing statistical evidence of distracted drivers causing a significant percentage of fatal car crashes best appeals to logos in support of laws against texting while driving.
Step-by-step explanation:
The statement that primarily appeals to logos, or reason, to support the position that laws forbidding texting while driving are necessary for public safety is:
"With distracted drivers causing eighteen percent of all fatal car crashes in America, prohibiting texting while driving is an obvious step in the right direction."
This statement uses statistical evidence to logically argue for the necessity of laws against texting while driving. It establishes a causal relationship between distracted driving and fatal car crashes, leveraging data to appeal to the reader's sense of reason.
