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.
When driving in fog, reduce your speed and turn on your headlights. Think about how far they can see and how long it will take you to stop. Keep an eye on your speedometer. Studies show that some drivers acclimate themselves to foggy conditions and unconsciously increase their speed over time.
