Hello I was working on my project that there are little cars that stop when there is something in front of them there is 2 script one of them controls the stop system another one moves the car

stop script :
local stopregion

while true do
	wait(0)
	stopregion = Region3.new(script.Parent.CheckPart1.Position, script.Parent.CheckPart2.Position)
	local partsinregion = game.Workspace:FindPartsInRegion3(stopregion, nil, 100)
	if #partsinregion >= 1 then
		repeat
			wait(0)
			script.Parent.MoveCarScript.Disabled = true
			wait(0)
		until #partsinregion == 0
		script.Parent.MoveCarScript.Disabled = false
	end
	wait(0)
end

move script :
while wait(0.001) do

script.Parent:SetPrimaryPartCFrame(script.Parent.CarBodyPart.CFrame + script.Parent.CarBodyPart.CFrame.lookVector * 0.05)

end

The Current Issue :

The Car Stops But It won’t Move Again And I Have NO IDEA how to fix this any help?
