Native Puertoricans are a kind and hard working folk. They are a proud people, and most happy to give you directions, if you ask them. Car rentals are available near some of the major hotels and airports. Detailed maps can be obtained there, or at gas stations and some novelty places. These days most parts of Puerto Rico are very accessible.
Major highways encircle the Island, and dissects the interior from north to south, and east to west.
Expect to locate most road signs immediately at, or very near the exits they refer to. Puerto Rico has its share of aggressive drivers. Stay away from heated traffic debates. Allow any vehicle that appears aggressive to pass you. The Puerto Rico Highway Police are as tough on violators here as police are in the United States.
