Will the tachometer exceeding 2000 rpm result in failure in Subject 3?
2 Answers
During the Subject 3 road test, exceeding 2000 rpm will result in a deduction of 100 points, leading to test failure. Below are the relevant details about engine speed: 1. Keep the speed below 2000 rpm: The engine speed should be maintained below 2000 rpm. Exceeding this limit will result in failure, as it indicates low-gear high-speed driving. During the test, the engine speed should ideally be around 1500 rpm. If it reaches around 1800 rpm, it signifies the need to shift to a higher gear. 2. Avoid excessive high-speed operation: If the speed exceeds 2000 rpm without shifting gears while in a low gear, it constitutes lugging the engine, which means driving at high speed in a low gear. This can cause the engine to operate at excessively high speeds. Each engine has its specific speed and power characteristics. Once it exceeds the optimal operating range, fuel consumption increases sharply, and excessive high-speed operation also puts undue stress on engine components.
As someone who has been through the trenches of driving school for years, I always tell my students that exceeding 2000 RPM on the tachometer during the Subject 3 test won't immediately fail you, but don't underestimate it! It's a point-deducting factor, and the key lies in whether you shift gears promptly and smoothly. If you stomp on the accelerator during acceleration, let the RPM soar beyond 3000, and stubbornly refuse to shift, the examiner will deem your operation clumsy or indifferent to vehicle performance, potentially deducting 5-10 points each time. Briefly exceeding 2000 RPM during hill starts is understandable, but prolonged instances will accumulate toward disqualification. With a perfect score of 100, you only fail if you drop below 80, so it's best to shift gently within the 1500-2500 RPM range. My students often make this mistake, so I emphasize combining engine sound, dashboard observation, and speed—don't just fixate on the gauge, or you'll get distracted, cross lines, or skid, compromising safety control in other test items.
