The excerpt that best achieves the purpose of informing people that seat belt laws are enforced nationwide is the following:
"People who live in rural areas might believe that the close-knit nature of their small town will get them out of a ticket. However, motorists should not think that knowing the officer who pulled them over will help them avoid a ticket."
This excerpt directly addresses a common misconception about enforcement in rural areas, emphasizing that knowing law enforcement officers does not exempt individuals from seat belt laws and the possibility of receiving a ticket. This highlights the enforcement aspect of seat belt laws across different locations.
