Many people want to put items in their vehicle when it is being transported. And while it seems simple enough, the truth is that you can only put so many things in your vehicle while it's being shipped. Carriers have strict weight restrictions they have to follow, and too many vehicles with too much weight can push a carrier overweight.
Any items put in a vehicle have to be in the trunk and you cannot have over 100 pounds of items total in the vehicle. If carriers are found to be overweight, delays will happen, so it's important to understand weight restrictions carriers operate under and what you can do to minimize potential problems in that area.
