Toll-free roads are nonexcludable, meaning that anyone can use them, and rival, meaning that the use of the road by one person reduces its availability for others. When the road becomes congested, it becomes rival as the more people use it the slower it gets and there is limited availability for others. Therefore, D is the correct answer.
