How many seconds should you hold the key when starting the engine in Subject 3?
4 Answers
You can release the key immediately after starting the engine in Subject 3. Below is relevant information about Subject 3: 1. Introduction to Subject 3: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed. 2. Test Content: The road driving skills test for Subject 3 generally includes: preparation before starting, light simulation test, starting, driving in a straight line, shifting gears, changing lanes, pulling over, going straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and night driving.
After years of teaching driving, this question has been frequently asked by my students. Especially during the starting procedure in the Subject 3 exam, the timing of releasing the ignition key is crucial. In actual operation, after turning the key to the start position, you should release it immediately within 1 to 2 seconds upon hearing the smooth engine start sound. Never delay, or the examiner may consider it improper operation and deduct points; keeping the key turned continuously may cause starter overheating and damage. Key steps include first confirming the gear is in neutral, depressing the clutch (for manual transmission vehicles), then swiftly starting the engine and releasing the key, immediately proceeding to the starting motion. During daily practice, I recommend beginners simulate this multiple times: practice quick movements in open areas to develop muscle memory, ensuring composure during the test. Cultivating good habits not only ensures exam success but also protects vehicle components, saving long-term hassle. Remember, Subject 3 evaluates safety awareness and standardized operations – a single detail mistake could be flagged, so never underestimate this simple step.
Speaking from my personal driving experience, starting the engine and releasing the key during daily starts is quite straightforward. After turning the key, the moment the engine hums to life, I’ve made it a habit to release it immediately—it’s just a matter of one or two seconds. If you hesitate for a few seconds, the starter motor will make an annoying noise, and in the long run, it could shorten its lifespan. I learned this the hard way with my first car—I often delayed releasing the key, and within less than a year, the starter motor failed. The repair shop said it was due to excessive load. The same applies to the driving test (Subject 3): the examiner checks whether you follow standardized procedures, and releasing the key quickly is a basic requirement. Before starting, check the seatbelt and mirrors, and once everything is ready, turn the key and release it in one smooth motion. Making this a habit leads to smoother driving and avoids unnecessary expenses. In short, it’s not about timing but following your instincts—once the engine starts, don’t waste time keeping the key turned.
As someone with long-term experience in automotive repair, let me explain from a technical perspective: When you turn the key to start the engine, electrical current is delivered to the starter motor, which engages the engine's flywheel. Once the engine is running normally—typically within one second after startup—you should release the key. Holding it longer increases the risk of overloading the starter. Starters are designed for brief operation; prolonged cranking can cause the coils to overheat and burn out. This isn't just a test requirement—it applies to everyday driving too: release the key as soon as you hear the engine fire. During the driving test's starting procedure, combining this with other actions like checking the dashboard for warning lights will enhance overall performance. Remember, the vehicle's electrical system is core—maintaining it properly can save you from repair headaches.
