A11. The following appeared in a letter to the editor of a newspaper:
“Last year when Washington County received a special appropriation for improving highway
safety, it spent all those funds to straighten sections of certain county roads.
Unfortunately, the number of traffic accidents in the county was actually higher than in the
previous year. Although Adams County received a smaller appropriation for improving highway
safety, it hired more police officers and enforced traffic laws more strictly. Last year
Adams County reported 15% fewer traffic accidents than during the previous year. Since money
for improving highway safety throughout the state is limited, we can achieve greater success
with less expenditure by using all such funds for stricter enforcement of speed limits.”
