I read the story about New York State spending $5.5 million of our money on infrared sensors to warn inattentive truck drivers approaching low bridges on the Northern State Parkway, Route 106/107 and the Seaford-Oyster Bay Expressway ["Over-height sensors set for area roads," News, May 14].
What a waste of money and resources. For much less than $1 million, I'm sure the state Department of Transportation could hang chains over every parkway entrance in the state. When a driver hears a chain rattle overhead, he would be warned of approaching danger.
The sensors will trigger new electronic signs warning truck drivers to pull over and contact New York State Police for help. If a driver can't read the sign that says "no trucks," how is a light sensor triggering another sign going to help? Low-tech is the best tech.
