Which of the following is true concerning the operation of a commercial vehicle?
  1. In some states, trucks and buses are required to drive at slower speeds than non-commercial vehicles, if posted to do so.
  2. Commercial vehicles are allowed to drive over the posted speed limit on some isolated roadways.
  3. Commercial vehicles are not allowed to use the "fast lane" when passing another vehicle.
  4. None of the above
Explanation
Answer: A - When operating a commercial vehicle or bus, drivers must be aware of posted speed limits that are less than limits placed on non-commercial vehicles. In some states, or certain areas, the speed limit for a commercial vehicle or bus may be as much as 15 mph slower than posted for non-commercial vehicles. When driving in these areas, drivers must be constantly aware of other motorists who may be attempting to pass them or merging into traffic at faster rates of speed.
