Help with car speed limit

Help and Feedback Scripting Support
1

So I have never made a car before and I’m having issues trying to script the car so that it won’t go over a certain speed, but rather maintain a speed that’s at the speed limit. My car relies on a bodyforce to accelerate / deaccelerate itself. Here is the script if you need it:

local Acceleration = Instance.new('BodyForce')
Acceleration.Force = Vector3.new(0,0,0)
Acceleration.Parent = script.Parent
local MaxSpeed = 40

script.Parent:GetPropertyChangedSignal('Throttle'):Connect(function()
	if script.Parent.Throttle == 1 then
		if script.Parent.AssemblyLinearVelocity.Magnitude >= MaxSpeed then
			Acceleration.Force = Vector3.new(0,0,0)
		else
			Acceleration.Force = script.Parent.CFrame.LookVector * 50000
		end
	elseif script.Parent.Throttle == 0 then
		Acceleration.Force = Vector3.new(0,0,0)
	else
		if script.Parent.AssemblyLinearVelocity.Magnitude >= MaxSpeed then
			Acceleration.Force = Vector3.new(0,0,0)
		else
			Acceleration.Force = script.Parent.CFrame.LookVector * -50000
		end
	end
end)
