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. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart.
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.
Among all weather conditions, fog is probably the most dangerous, so if you are driving in foggy weather, lower your speed and turn on your low-beam headlights. If the fog becomes so thick that you can barely see, pull safely and completely off the road.
