Should an automatic transmission car be started in P gear or N gear?

An automatic transmission car should be started in P gear. Below is relevant information about P gear and N gear: 1. N (Neutral) gear introduction: Neutral N is equivalent to the neutral gear in a manual transmission, which can be used when starting or towing. When waiting at traffic lights or in traffic jams, the gear selector is often kept in D position while the brake is pressed. If the stop is very brief, this is acceptable, but for longer stops, it's better to shift to N position and engage the parking brake. 2. P (Parking) gear introduction: When this gear is engaged, the wheels are mechanically locked to prevent rolling. The vehicle must be completely stopped before using P gear, otherwise the mechanical parts of the automatic transmission may be damaged. Additionally, automatic transmission cars usually have a safety switch that only allows the engine to be started when in "P" or "N" gear, to prevent sudden forward movement if accidentally started in other gears.

I've been driving for over 20 years, and when starting an automatic transmission car, you must always select P gear to ignite. Simply put, the reason is: P gear is the parking gear, which completely locks the transmission, preventing the vehicle from moving; starting in N gear leaves the wheels free, and if you don't firmly press the brake or are on a slope, the car might roll away, leading to an accident when it's too late. The manual emphasizes that starting in P gear is the safest, as it utilizes the car's designed protection mechanism. I never make an exception in my daily driving, and developing this habit gives me peace of mind. Some might start in N gear during car washes for easier pushing, but that's in a professional setting and unnecessary in daily life. In short, safe driving starts with the correct ignition.

As a veteran driver with nearly 30 years of experience, I always insist on starting an automatic transmission car in the P (Park) position. Why? In P gear, the vehicle is completely locked, eliminating any risk of rolling during startup. While starting in N (Neutral) might seem feasible, it requires you to firmly press the brake at all times. A momentary lapse in attention could lead to the car moving and causing trouble. In my younger days, I once forgot I was on a slope when starting in N gear, and the car rolled, nearly hitting a wall—a lesson I’ll never forget. Since then, I’ve only taught beginners to start in P gear, making it a reflex for peace of mind and reliability. Remember, starting in P is a fundamental practice that adds an extra layer of safety.

As a regular car owner, it's best to start an automatic transmission vehicle in P (Park) gear. Starting in P ensures the car is locked and won't move, prioritizing safety. Starting in N (Neutral) leaves wheels free, risking accidental rolling. Manuals recommend P gear, making it an easy habit to form. Following this routine ensures worry-free daily driving.

Those who know a bit about cars understand that automatic transmissions should be started in P (Park) gear. The P gear mechanically locks the wheels, ensuring no movement during ignition, whereas N (Neutral) lacks this function and relies entirely on the braking system. Older car models might allow starting in N gear, but modern designs prioritize P gear ignition to protect transmission performance. I’ve always followed this practice to minimize risks and maximize efficiency. Beginners are advised to master the correct operating procedures rather than taking shortcuts.

When driving an automatic transmission car, always start the engine in P gear: this has become my instinctive habit. P gear provides the most reliable anti-roll protection, especially on slopes or in heavy traffic; starting in N gear is possible but highly risky, requiring extra attention to the brakes. Developing good practices makes driving more worry-free, and I've never had any issues by sticking to this long-term. Remember, safety is always the starting point.
