PITTSBURGH —

When the roads are too tough for school buses to get around, superintendents will delay start times or cancel classes.  But fire trucks don't have that luxury.  When they're needed, they're needed fast.

Channel 11 reporter Jennifer Tomazic was with firefighters as they got their trucks moving on snow-covered streets.

The firefighters show Tomazic the chains they use to stay safe.  Watch the video.
