What happens if you start the car without shifting to neutral?

It mainly depends on whether it's an automatic or manual transmission. Manual transmission vehicles are unaffected. The consequences of starting an automatic transmission car in neutral and the correct method for parking and turning off the engine are as follows: 1. Turning off the engine in neutral poses no issues for the car. The engine should only be turned off in N (neutral) or P (park) gear. Turning off the engine in D (drive) or R (reverse) gear can damage the transmission. The prerequisite for neutral is ensuring the car is on level ground to prevent rolling. 2. The correct method for parking and turning off the engine is to first shift from the driving gear to N gear, pause for 0.5-1 second in N gear, then directly shift to P gear, and finally apply the handbrake. 3. This operation ensures the gearshift doesn't switch twice consecutively. The action should be smooth, as each gear has a detent. Although you pass through R gear, you're not actually shifting into R gear.
As a seasoned long-distance driver, I know that safety is the top priority when driving. If you attempt to start the engine without shifting to neutral, especially in an automatic transmission car, the engine might try to start while the car is in D (Drive) or R (Reverse) gear. This can cause the vehicle to lurch forward or backward suddenly, particularly on slopes, leading to loss of control and potential collisions with people or objects—resulting in an accident. Many cars nowadays come with safety locks that prevent the engine from starting if the gear isn’t in the correct position—a brilliant design that eliminates unnecessary risks. I once nearly made this mistake myself, so I’ve since developed the habit of always shifting to P (Park) before starting the engine. Such small details can’t be overlooked; developing good habits ensures safety and peace of mind while driving. Additionally, regularly checking your car’s gear system can help prevent problems before they arise.
I come from a car repair background and have seen many vehicles with issues caused by improper starting. Starting without shifting to neutral can lead to numerous problems. If an automatic transmission car is started in D gear, the starter may burn out, and the transmission gears can get stuck, resulting in costly repairs. Even worse, the engine bears excessive load, shortening the lifespan of its components. Why? Because the high current during startup, combined with incorrect gear engagement, leads to improper power transmission. I advise against trying it—always shift to P or N gear before ignition. This habit saves time, effort, and money. Regularly check your car’s manual to understand the gear mechanism, and you’ll avoid unnecessary trouble. Repairs can be complex and cost thousands—definitely not worth the risk.
I'm a young car enthusiast, let's talk about something fun. There's a big difference between new and old cars. With classic antique cars, you might actually start the engine without shifting to neutral, causing the car to jerk forward suddenly, which can be terrifying. But modern cars are a different story—they're controlled by computers, so if the gear isn't in the right position, the start button won't even respond. This design prevents accidents and is quite thoughtful. Simply put, P (Park) is the preferred gear for starting, though N (Neutral) also works—just double-check before ignition. Develop this habit; no need to be overly technical, just get comfortable with it.
