If you’ve ever glanced at your car dashboard and noticed a symbol or letters like “ACC”, you might have paused and wondered what it stands for. Is it something serious? Or just a simple car feature? Don’t worry — you’re not alone. Many drivers see “ACC” for the first time and get confused about whether it’s a warning or a helpful function.
Quick Answer:
In cars, “ACC” usually stands for Adaptive Cruise Control. It’s a driver-assist feature that automatically adjusts your speed to maintain a safe distance from the vehicle ahead. It’s not a warning — it’s a convenience and safety feature.
What Does ACC Mean in a Car?
ACC, or Adaptive Cruise Control, is an advanced version of traditional cruise control. While regular cruise control keeps your car at a fixed speed, ACC uses sensors to detect vehicles in front of you and adjusts your speed automatically to maintain a safe following distance.
Example:
“I turned on ACC on the highway, and my car automatically slowed down when traffic ahead reduced speed.”
In short:
ACC = Adaptive Cruise Control = Automatic speed adjustment for safer driving
