--- name: VehicleSeat last_updated: 2026-06-10T23:09:12Z inherits: - BasePart - PVInstance - Instance - Object type: class memory_category: Instances summary: "A seat object that can be used to control a vehicle." --- # Class: VehicleSeat > A seat object that can be used to control a vehicle. ## Description The `VehicleSeat` objects welds a player to the seat when the player touches the seat. It then forwards the movement inputs to any connected motor joints, allowing control of a vehicle. While `VehicleSeat` is great for making simple vehicles they do have some limitations. Movement control will only detect motors connected directly to the vehicle seat, or through another rigid connection. This means that if you have a wheel connected to a beam which is then welded to the seat it will work fine, however if you have the wheel connected to a part, which is connected by a hinge to the rest of the car, it will not work. ## Properties ### Property: VehicleSeat.AreHingesDetected ```json { "type": "int", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": false, "can_save": false }, "thread_safety": "ReadSafe", "category": "Control", "capabilities": [ "Basic", "AvatarBehavior" ] } ``` Displays how many hinges are detected by the `VehicleSeat`.

Will refresh back to `0` (null) unless constantly set. ### Property: VehicleSeat.Torque ```json { "type": "float", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Control", "capabilities": [ "Basic", "AvatarBehavior" ], "simulationAccess": true } ``` How fast the vehicle will be able to attain [MaxSpeed](/docs/reference/engine/classes/VehicleSeat.md). The greater the number, the faster it will reach the maximum speed. ### Property: VehicleSeat.TurnSpeed ```json { "type": "float", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Control", "capabilities": [ "Basic", "AvatarBehavior" ], "simulationAccess": true } ``` The speed at which the vehicle will turn. Higher numbers can cause problems and are not necessarily better. ## Methods ### Method: VehicleSeat:Sit **Signature:** `VehicleSeat:Sit(humanoid: Instance): ()` Forces the character with the specified [Humanoid](/docs/reference/engine/classes/Humanoid.md) to sit in the `VehicleSeat`. *Security: None · Thread Safety: Unsafe · Capabilities: Basic, AvatarBehavior* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `humanoid` | `Instance` | | The [Humanoid](/docs/reference/engine/classes/Humanoid.md) being forced to sit in the `VehicleSeat`. | **Returns:** `()` ## Inherited Members ### From [BasePart](/docs/reference/engine/classes/BasePart.md) -
