# How to enter and exit from a vehicle
Any vehicle can be controlled by the player, basically the entry system will disable the character controls and enable the vehicle control.
To drive a `Vehicle` the character must have the `Drive Vehicle System`
| Property | Description |
| -------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| Start Vehicle | A default vehicle to start driving |
| Enter Vehicles Enabled | If true, the character can enter and drive vehicles. |
| Exit Vehicles Enabled | If true, the character can exit from the `Vehicle` if is driving. |
| Disable Character On Enter | Disable the character after enter on the vehicle, usefull for vehicles that not have IK settings for drive animations. |
| Delay To Re enable Action | The time to reactive enter vehicle action after start enter or exit of some `Vehicle`. Can't be less than 0.1. |
| Max Vehicle Speed To Exit | Don't allow to exit from a vehicle on high speeds. |
| Ground Layer | The layer used to detect the ground to set the character position when exit from the current vehicle. |
## How vehicle detection works ?
Vehicles must have a child trigger with a specific tag and layer, the trigger must have a JU Vehicle Interactable to work.
The Player needs to have a [JU Interaction System](https://julhiecio.gitbook.io/ju-tps-documentation/game-development/new-interaction-system), which will detect the vehicle's trigger.
## Characters without driver animations
For simple games you can disable the character instead of use complex animations and IK system.
## Simple Character Driver Animation
If you have a character animation that match with the vehicle model you can use the `JUVehicleCharacterIK` to set the character position inside the vehicle.
## Advanced Character Driver Animations with IK
You can use foot and hand IK on vehicles if you want, very useful to make wheel steer, motorcycle inclination animation or foot placements.
To use it, the character must have the `DriverProceduralAnimation` component, it's is responsible by the IK system.
Furthermore, you need to have assigned all the IK target positions on the `JUVehicleCharacterIK` of the vehicle and the IK weights configured.

Tip: if you see a prefab of a vehicle you will notice hand, foot, sphere or humanoid character gizmos. You can copy these GameObjects, paste them into your new vehicle, position them and assign them to the above parameters.
{% endhint %}
