Most major roads will be in much better shape than they were 24 hours ago, but drivers should still drive slower and watch for patches of ice.
FOX 4's Chip Waggoner said there have been several crashes already. On southbound 35W at Highway 114 there was a fiery crash caused by ice. In West Dallas, northbound Loop 12 to Interstate 30 was closed because of a jackknifed big rig.

Road crews with TxDOT and the NTTA will continue to work around the clock to monitor and treat the roads.
Potholes could be a bigger problem for most drivers. The latest round of winter weather has caused a lot of flat tires already.
"This is my third tired shop. I'm riding around on a rigidity tire that was busted on the freeway. Now my rim is messed up because I'm riding around trying to get it fixed," said Gregory Brown, who hit a pothole on Interstate at Belt Line Road in Carrollton.
Residents in the city of Dallas can report potholes by calling the non-emergency number 311.
Airlines are also hoping to return to a regular schedule, but must first rebook all the people whose flights were canceled because of the winter storm.
DART and the T in Fort Worth are both running on regular schedules. Delays are still possible because of re-freezing on the roads.
