When the sun goes down in Tulsa, the only lights you’ll see on the highways are headlights.
To save money, the city turned off most of the highway lights back in November.
People are talking about it on twitter and facebook.
One person wrote: "I think it's really a safety hazard. I exited a highway one night, and it was so dark I almost ran the stop sign."
Someone else wrote: "Saving money at the risk of public safety? I'm sure there are other non-essential cuts that can be made."
Drivers are complaining to the city and to police.
"I know there's some concern," says Officer Craig Murray.
He did some checking to find out if driving in the dark is causing more crashes.
The city turned off the lights November first.
From then until December 31 there were 72 crashes on the Broken Arrow expressway.
43 percent of those happened after dark.
Officer Murray checked the same time frame during the previous year.
The numbers were similar – 73 crashes and 45 percent after dark.
"We're very fortunate... there could've been a lot more collisions," Murray said.
"We have to do what we can do to save some money."
Some don't mind the dark highways. One driver wrote this on facebook: "It didn't bother me. I used my headlights."
But most say – turn the lights back on.
