Sorry I’m a bit late by 2 years, but I thought this would be helpful for anything coming back. You can also get module, and use it for cars without needing to load, and you normally need to call it to get an internal module.

local Module = require(game.ReplicatedStorage.MyModule)
Module.MyFunction(MyParameters)
Or, more simple.
require(game.ReplicatedStorage.MyModule).MyFunction(MyParameters)
You can also use it like this.
require(game.ReplicatedStorage.MyModule).MyFunction
if true then print("Returned true!") end
As long as you have return true somewhere in your function.
Again, sorry for the late post, thought it would be helpful for anyone looking for this in old topics.
