As part of the pre-trip inspection, drivers should check the oil pressure gauge to ensure:
  1. That the oil pressure is not increasing
  2. That the oil pressure is increasing
  3. That the warning light is on and stays on
  4. None of the above
Explanation
Answer: B - When performing an oil gauge check drivers should ensure that the gauge shows the oil pressure increasing to its "Normal" level. They must also ensure that the oil pressure warning light goes off. If the pressure does not increase or the warning light stays on, maintenance is required before moving the vehicle. When oil pressure problems arise, drivers should immediately turn off the engine to prevent damage to the engine.
