Relates to yellow signals at traffic intersections

This bill requires all traffic-control signals in New York State to be examined and certified as accurate every two years. It directly affects the New York State Department of Transportation (DOT), local governments, and entities that install signals with DOT permission (such as schools or private property entrances). The key provision mandates biennial accuracy checks to ensure signals function correctly, replacing prior maintenance standards. This applies to all signals under DOT jurisdiction, including those installed before 1986 under specific conditions. The change focuses on routine safety verification without altering signal operation rules.
