Forklift Test questions 51–60 with the correct answers and explanations — Inspection & Maintenance practice from the official-based bank. Free, no sign-up.
Quick answer: below are 10 questions (51-60) with answers and explanations, sourced from official public material or written to the official outline. The format matches the timed practice test exactly, so what you learn here transfers one-to-one.
Questions 51-60
CautionQuestion 51: During your pre-shift check you find the brakes feel soft. What does the standard require?
- A. Operate with reduced loads until the next scheduled service
- B. Take the truck out of service until it has been restored to safe operating condition ✓
- C. Finish the shift, then report it to maintenance
- D. Switch to a different truck for heavy loads only
Answer: B — Take the truck out of service until it has been restored to safe operating condition. If at any time a truck is found in need of repair, defective, or in any way unsafe, it shall be taken out of service until restored to safe operating condition. 'Finish the shift first' is exactly the judgment the rule removes from the operator's hands. Official outline
CautionQuestion 52: A forklift has a visible fuel system leak. May it be operated?
- A. Yes, outdoors only
- B. Yes, if a fire extinguisher is mounted on the truck
- C. No — no truck shall be operated with a leak in the fuel system until the leak has been corrected ✓
- D. Yes, at reduced speed with the engine bay open
Answer: C — No — no truck shall be operated with a leak in the fuel system until the leak has been corrected. No truck shall be operated with a leak in the fuel system until the leak has been corrected. Fuel vapor plus ignition sources is the fire scenario the entire standard is built to prevent — a leak is an automatic out-of-service. Official outline
CautionQuestion 53: When may a fuel tank be filled?
- A. Only while the engine is running, so the pump sees live pressure
- B. Only when the engine is not running, and spillage shall be avoided ✓
- C. At any time, using a grounded nozzle
- D. Never — tanks must be swapped, never filled
Answer: B — Only when the engine is not running, and spillage shall be avoided. Fuel tanks shall not be filled while the engine is running, and spillage shall be avoided. Any spilled oil or fuel must be washed away or fully evaporated and the fuel tank cap replaced before the engine restarts. Official outline
CautionQuestion 54: How may you check the electrolyte level in a storage battery or the gasoline level in a tank?
- A. With a lit match or lighter for a quick look
- B. By shaking the battery to hear the level
- C. With any flashlight, including flame-type lanterns
- D. Never with an open flame ✓
Answer: D — Never with an open flame. Open flames shall not be used for checking electrolyte level in storage batteries or gasoline level in fuel tanks. Battery electrolyte releases hydrogen gas, and gasoline gives off flammable vapor — both find an open flame immediately. Official outline
WarningQuestion 55: The eleven designations of industrial trucks in the standard are:
- A. A, B, C, D, E, F, G, H, J, K, L
- B. D, DS, DY, E, ES, EE, EX, G, GS, LP, and LPS ✓
- C. Classes 1 through 11
- D. Type I, Type II, Type III, Type IV, and Type V
Answer: B — D, DS, DY, E, ES, EE, EX, G, GS, LP, and LPS. The standard defines eleven designations: D, DS, DY (diesel series), E, ES, EE, EX (electric series), and G, GS, LP, LPS (gasoline and LP-gas series). The letters encode the power source and the level of fire safeguards, which decide where each type may be used. Official outline
WarningQuestion 56: How often must industrial trucks be examined?
- A. Weekly, by the maintenance department
- B. Annually, during the state inspection
- C. Before being placed in service, at least daily — and after each shift where trucks are used on a round-the-clock basis ✓
- D. Only after any repair work
Answer: C — Before being placed in service, at least daily — and after each shift where trucks are used on a round-the-clock basis. Trucks must be examined before being placed in service, at least daily; where they run around the clock, the examination happens after each shift. A truck that fails the examination is not placed in service, and defects found are immediately reported and corrected. Official outline
CautionQuestion 57: Who must make repairs to a powered industrial truck?
- A. The operator, using the tool kit on the truck
- B. Authorized personnel only ✓
- C. Any employee familiar with engines
- D. Only the original manufacturer's factory technicians
Answer: B — Authorized personnel only. Any truck not in safe operating condition is removed from service, and all repairs are made by authorized personnel. The operator's role is to find and report defects — not to improvise repairs on the floor. Official outline
WarningQuestion 58: Where may repairs involving fire hazards to the fuel and ignition systems be conducted?
- A. Anywhere outdoors
- B. In any Class I, II, or III location with ventilation
- C. Only in locations designated for such repairs ✓
- D. In the aisle where the truck is parked
Answer: C — Only in locations designated for such repairs. Repairs to fuel and ignition systems that involve fire hazards are conducted only in designated locations — and no repairs at all are made in Class I, II, and III (hazardous) locations. Fuel-system work migrates to the designated bay, not to wherever the truck happened to stop. Official outline
WarningQuestion 59: Before repairs to the electrical system, what must be done?
- A. The battery must be disconnected ✓
- B. The truck must be driven to warm the circuits
- C. The overhead guard must be removed
- D. Nothing special — electrical repairs are routine
Answer: A — The battery must be disconnected. Trucks needing electrical-system repairs have the battery disconnected prior to the work. Live terminals plus a wrench or a dropped metal part equal arc flash and ignition risk. Official outline
WarningQuestion 60: Replacement parts installed on a powered industrial truck must be:
- A. The cheapest available equivalent
- B. Only parts re-manufactured by OSHA-approved shops
- C. Any parts that physically fit
- D. Equivalent as to safety with those used in the original design ✓
Answer: D — Equivalent as to safety with those used in the original design. Parts requiring replacement are replaced only by parts equivalent as to safety with those used in the original design. A bargain-brake or off-spec mast chain fails this rule even if it bolts on cleanly. Official outline
