Cars drive too fast down my street. Can a stop sign be installed to slow traffic?
No. The purpose of a stop sign is right-of-way assignment, not speed control. Certain warrants have to be met before a stop sign is installed. Engineering studies have shown that unwarranted stop signs contribute to speeding, because the driver tries to make up for time lost due to stopping. Other measures (as mentioned above) can be taken to correct a speeding problem.
