Here in Texas, everyone knows the bridges and overpasses will be icy in the type of weather we currently have. To that knowledge, they will maintain their speed until they approach a icy patch, then apply the brakes firmly.
A few years ago, I watched this on TV and after sliding sideways over a bridge, the car left the roadway to the back yard of a house , and wiped out the single dog house situated there. Came to rest just shy of the patio.
