In an automatic transmission car, which gear must be in to start?

Starting in Park is required because the Park position engages a locking mechanism that prevents the transmission’s output shaft from turning, keeping the car from rolling while the engine starts. This safety lock ensures you won’t lurch forward or backward as the engine cranks. Driving or Reverse would leave the transmission connected to the wheels, which could move the car the moment the engine starts. Neutral can sometimes be used in some vehicles to start since there’s no load on the drivetrain, but Park is the standard starting position and what most cars require for a safe start.
