Which of the following statements is true about longer vehicles, such as those with sleeper compartments?
  1. When making right turns, these vehicles need more room.
  2. When making right turns, these vehicles need less room.
  3. There is no difference in turning radius between normally sized tractor trailers and long wheelbase tractor trailers.
  4. None of the above is a true statement.
Explanation
Answer: A - Drivers of long wheelbase tractor trailers must always be aware that these vehicles require more room when making a right turn. It is essential that drivers who are accustomed to operating short wheelbase tractor trailers get some practice turning both directions before operating a long wheelbase rig on public roads. The major causes of right hand turn accidents in tractor trailers are drivers did not swing out far enough or drivers that swung out too far. There is little room for error when making right hand turns.
