Is the engine speed not allowed to exceed 2000 rpm in Subject 3?

Engine speed should be kept below 2000 rpm, exceeding which will result in a failing judgment. Here are the relevant details: Introduction: Engine speed exceeding 2000 rpm is considered low-gear high-speed. During the test, engine speed should be maintained around 1500 rpm. If the engine reaches around 1800 rpm, it indicates the need to shift up. Excessive fuel consumption: Failing to shift gears when exceeding 2000 rpm in low-speed gears constitutes lugging the engine. Low-gear high-lug operation forces the engine to run at excessively high speeds. Each engine has its specific speed and power characteristics. Once it exceeds the optimal operating range, fuel consumption increases sharply. Additionally, ultra-high-speed operation places excessive stress on engine components.
During the driving test (Subject 3), the instructor always reminds me to keep the engine speed below 2,000 RPM, with the main goal of cultivating smooth driving habits. This isn't necessarily a nationwide regulation, but many driving schools recommend students maintain this range because higher RPMs increase engine noise and fuel consumption, which may lead the examiner to perceive your driving as unstable or involving sudden acceleration. When shifting gears, exceeding 2,000 RPM can easily cause stalling or untimely gear changes, resulting in point deductions during the test. From my experience, the best practice is to shift up to second or third gear as soon as possible after starting, keeping the RPM between 1,500 and 2,000; press the accelerator lightly and practice gear-shifting timing more. Developing this habit can also extend engine lifespan and make daily driving easier and safer. Remember, the test evaluates control—details are crucial.
In driving tests, there is no strict prohibition against exceeding 2000 RPM, but operationally I was always advised to avoid it during my driving lessons. High RPM increases unnecessary wear, especially in low-speed sections like urban road tests where the engine's power output becomes unstable at high revs, potentially leading examiners to believe you don't understand shift timing. Ideally, maintain 1500-1800 RPM for smoother starts, fewer stalls, and better fuel efficiency. Variations exist between different car models - smaller displacement vehicles can deliver power at lower RPMs, so don't fixate too much on numbers; focus on practicing shift rhythm. This habit has also helped me drive more economically in daily life after passing the test.
