What does the tachometer indicate?

• A. Indicate engine speed in RPM
• B. Indicate vehicle speed
• C. Show fuel level
• D. Display temperature

Answer: (A)

Engine speed in revolutions per minute (RPM) is what the tachometer indicates. It shows how fast the engine is turning, so you can shift gears at the right moment and avoid over-revving. Watching the RPM helps you stay in the engine’s power range for smoother, more controlled acceleration. This gauge is different from the speedometer (vehicle speed), the fuel gauge (fuel level), and the temperature gauge (engine temperature). If you approach the redline, you’ll know it’s time to upshift to protect the engine.
