Why should you avoid driving into the space immediately surrounding a large vehicle?

• Because large vehicles need twice as much distance to stop, especially on wet or icy roads
  Explanation:

  "Drivers of large vehicles try to keep a safety cushion of space around them. A large truck may need twice as much distance to stop as an automobile or a motorcycle, especially when roads are wet or icy. Do not drive into the space immediately surrounding a large vehicle. Do not pull in front of a large vehicle and slow down or stop suddenly. The driver will have too little room to stop and will crash into you or may risk “jackknifing” by trying to stop suddenly at highway speeds."
• Because large vehicles can stop more easily than cars
• Because large vehicles are less likely to be involved in accidents
• Because large vehicles can always stop in time, even at high speeds
