LAS VEGAS -- Motorists know red means stop and green means go, but some drivers are getting confused by newly-installed flashing yellow arrow lights at hundreds of valley intersections.
Millions of dollars are being spent on more than 400 new traffic lights to reduce car crashes.
Before the flashing yellow arrow, we had a solid green light, and drivers yielded when making unprotected left turns.
But all these changes are giving some drivers mixed signals.
Flashing yellow arrow lights are designed to put the brakes on traffic trouble.
Motorist Cindy Williams said she sometimes finds herself dodging danger on Desert Inn Road and Arville Street.
"It's supposed to be a caution light, not a light saying I can go," she said. "I think it's dangerous. I've witnessed the accidents."
She said she sees more driver confusion, but studies show flashing yellow arrow lights are safer and cut down on crashes.
