One of the most important things, besides the mount, is to have a sturdy flagpole. The last thing you want to happen is for the flag pole to break off and become a flying object on a highway. It’s important that you stay safe and keep other drivers safe. Be sure to select a pole and grommets that are solid and will not fail. Get an extremely rigid pole made of metal that will not bend or break off. Try to refrain from taking the vehicle on highways at a fast rate of speed when the flag is mounted. Most flags and flag poles aren’t made to withstand winds from driving at fast speeds.
