The High Five is not a good option for drivers, with sanding trucks having difficulties reaching the overpasses.

Many people who ventured out onto Dallas overpasses, like the High Five, have found their wheels spinning.

Cars blocking traffic have created problems, too, some of which are overturned vehicles.

Dallas police reported 165 minor wrecks, 99 injury wrecks and 104 injury wrecks on freeways.

A flipped pickup truck on I-35E backed up traffic for miles earlier today, and didn’t allow a much-needed sand truck to cover the road.

The city started with 35 sanding trucks, but has ended the day with 56 trucks and 125 working employees.

Temperatures continue to drop as the night goes on, but so does the speed at which travelers go.

CBS 11 is told the city is doing its best to prepare for the morning commute – but motorists are still asked to be as safe as possible.
