BATON ROUGE- Lawmakers deferred a bill that would change traffic signals across the state, making it mandatory for yellow lights to run at least 5 seconds.
Traffic engineers say the law could negatively affect traffic patterns.
"We would have to reevaluate a lot of the signal timing, every second that you add to the yellow, you have to take from the green, and many of our congested intersections, the times would have to be adjusted and you know you'd just have less green time," said Sarah Paul Edel, a traffic engineer in Baton Rouge.
Edel says the lights are already calibrated according to mathematic equations and there's no need to change anything.
"They're founded in science and have been tested and they are what they need to be already, ours are set between 4 and 6 seconds," said Edel.
Nationally, the absolute minimum a yellow light can run is 3 seconds, in Baton Rouge the minimum is four seconds.
