Does an Automatic Transmission Car Move When You Release the Brake?
1 Answers
Under normal circumstances, when the gear is in D (Drive), R (Reverse), or L (Low), the vehicle will move upon releasing the brake. However, even in these gears, there are a few special cases where the car may not move: 1. First Scenario: The vehicle is on a very steep slope. Due to inertia, the resistance increases, and the car will only move if the forward driving force is greater than the resistance (except when utilizing inertial force). Principle: If the forward driving force is less than the downward slope force and resistance, the car won't move. 2. Second Scenario: Transmission settings of certain models. Some car models have transmission settings where the vehicle won't move unless the accelerator is pressed. Even if the gear is in D, the car will automatically disconnect the power link, effectively being in neutral, unless the accelerator is engaged.
