When approaching or entering a curve, which of the following is true?
  1. Brake hard within the curve to reduce speed.
  2. Slow to safe speed before entering the curve.
  3. Posted speed limits for curves do not apply to commercial vehicles.
  4. Gear selection is not important in a curve.
Explanation
Answer: B - When approaching or entering curve, commercial drivers must slow to a safe speed before entering the curve. It is very dangerous to brake while in a curve because this can cause the wheels to lock up. Posted speed limits apply to all drivers, but large commercial vehicles may wish to reduce their speed below this posted level for safety reasons. It is also important to be in the proper gear that will allow the driver to accelerate in the curve if needed.
