Watching for standing water on roadways should be a main concern of all drivers across the state.

The temperatures in Tulsa are expected to remain in the mid-30s, and Operation Slick Streets is in effect in Tulsa. Operation Slick Streets means police will not respond to a wreck if there are no injuries. They advise drivers to take pictures of the damage then move cars out of the roadway as quickly as possible.

In addition to the damage, take pictures of the person's license plate, their insurance verification card and even their driver's license. Once you have all the information, go to a QuikTrip and get a collision report. Fill it out and drop it by any police station or mail it in. Or you can go to TulsaPolice.org and complete it online.
