What are the ignition switch positions?

Ignition switch positions include START position, ON position, ACC (accessory) position, and LOCK position. The ignition switch is the control for a vehicle's ignition system, enabling the main circuit of the ignition coil to be freely turned on or off. Methods to start the ignition switch: 1. After inserting the key into the ignition switch, briefly pause at each position for 1-2 seconds, during which you can hear the sound of electrical devices powering on; 2. Proceed to the next position. Some vehicles allow direct entry to the ON position, after which you should wait approximately 6 to 7 seconds for all electrical systems to fully activate before turning the key to the START position to ignite the engine.
I remember from my first time driving until now, the ignition switch has several different positions that are particularly important for safe operation. The most basic is the OFF position, which completely shuts off the engine and all electrical circuits. After removing the key, the steering wheel locks for anti-theft purposes. Next is the ACC (Accessory) position, which allows the radio or charging ports to work without starting the engine—quite practical when listening to music in parking lots, but not recommended for prolonged use to avoid quickly draining the battery. The ON position is reached by turning the key slightly further, where all dashboard lights illuminate, and the car is ready to start but the engine hasn’t fired up yet. Finally, the START position is a brief turn to crank and ignite the engine. Every time I drive, I first turn to ON to check the indicator lights and confirm the car’s condition is normal before starting, avoiding sudden malfunctions. When locking the car, I also make it a habit to check if it’s returned to OFF to protect the electrical circuits and devices.
As someone who enjoys tinkering with cars, I find the ignition switch positions quite ingeniously designed, with LOCK, OFF, ACC, ON, and START positions. LOCK serves as an anti-theft function after parking and removing the key, OFF completely cuts off power, ACC allows the use of accessories like charging a phone, ON puts the car in a ready state activating components like the fuel pump, and START is for actually igniting and starting the engine. When I inspect my car, I often use ACC to test electronic devices, but I avoid randomly switching positions to prevent damaging the switch. It's best not to skip the ON position and go straight to START when starting the engine to protect the system from shock. Over time, drivers become familiar with these details to avoid unexpected stalling or failure to start.
When I was learning to drive, the instructor repeatedly emphasized the ignition switch positions, saying it's the foundation of driving. The LOCK position is where you remove the key to lock the steering wheel against theft. OFF means completely shutting down and stopping the engine. ACC turns on accessories like the audio system without starting the car. ON is the preparatory position that powers up the system for fault light checks. START is the rightmost position; turn to it to start the engine, then release back to ON. Beginners should practice the key-turning sequence patiently to ensure safety first. Before starting, switch to ON to let the car warm up for a few seconds for better performance, and avoid dangerous misadjustments while driving. Simply remembering these steps can help reduce mistakes and save time.
