.Touched script isnt working, im at dead ends!! Any help?

So i made this script but it isnt working. please take a look:

script.Parent.Touched:connect(function(hit)

if hit.Parent.Name == "B" then
	print("b touched")
		script.Parent.Parent.Parent.VechicleSeat.MaxSpeed = 0
		end
end)

The part B is touching it because ive seen it. Ive tried it with other stuff but it doesnt work still. I know it isnt working because its not printing anything. Ive also tried hit.Name and it still dont work. Any ideas?

The reason is that you didn't put If hit.Parent:FindFirstChild("Humanoid") then

So Heres the step

1.Put the script into a brick then copy this into script

Part.Touched:connect(function(HIT)
	local H = HIT.Parent:FindFirstChild("Humanoid")
	if H then
		script.Parent.Parent.Parent.VechicleSeat.MaxSpeed = 0
	end
end)

There you go! If this helped then accept the Answer please.

Ive given up so im just going to use wait inside the scripts

Thank you to everyone that tried to help :)
