thrombotic thrombocytopenic purpura. Description. Thrombotic thrombocytopenic purpura is a rare disorder that causes blood clots (thrombi) to form in small blood vessels throughout the body.

âTHE MOST IMPORTANT DRIVING TECHNIQUE TO AVOID CRASHES WHEN DRIVING IN ICY OR SNOWY CONDITIONS IS REDUCING SPEED AND INCREASING FOLLOWING DISTANCEâ. When you are driving on ice, you have to keep in mind that your wheels don't have as much traction as they do when you are driving on dry pavement.
The California DMV Driver Handbook. A road that is normally safe can become dangerous when it's slippery. Ice and packed snow on the road can cause the car to skid, especially if you are driving too fast or going downhill. If you do go into a skid, ease off the gas pedal, stop braking, and turn the steering wheel in the direction of the skid.
