Before traffic safety signs are placed, municipalities will commission an engineering study to gauge its necessity and usefulness in a particular location. After all, no one would want to travel roadways where signs are placed haphazardly and without just cause. Doing so would eventually cause some drivers to fail to respect the traffic signs, possibly causing traffic incidents instead of preventing them.
