Which fluid levels are typically checked during a pre-trip?

• A. Engine oil, coolant, power steering fluid, windshield washer fluid, and sometimes hydraulic fluids.
• B. Transmission fluid and brake fluid only.
• C. Only the fuel level.
• D. Hydraulic oil only.

Answer: (A)

During a pre-trip, you’re making sure the fluids that keep the engine, cooling system, steering, and visibility functioning are at proper levels. The typical checks include engine oil for lubrication, coolant for temperature control, power steering fluid for smooth steering, and windshield washer fluid to maintain visibility. If the vehicle uses hydraulics, you also check the hydraulic fluid level because low levels can hinder equipment operation. This broad set ensures you’re covered for the most critical safety and performance needs on the road. Other options that focus on only one or two fluids miss essential items like lubrication, cooling, steering, and visibility, so they’re not sufficient for a proper pre-trip.
