Puerto Rican road maps are hard to come by throughout the country and foreign navigation systems may not operate well. In other words, you could end up completely lost. Hope you know Spanish! But if "hola" is as far as you can go, then it's a good idea to take a Spanish phrasebook or dictionary with you in case you need to ask for directions. You could also try printing out directions from an online map source before heading out on the road.
A lot of road signs are identifiable by symbols used in other countries, but there can be differences. For instance, distance is in kilometers, but speed limits are measured in miles.
It's often reported that drivers largely ignore road markings and traffic signals, including red lights. Naturally, this can make for some dangerous conditions, and even the most seasoned drivers should keep their guard up. Even when you have a green light, slow down to make sure drivers in the other lane are not running their red light, particularly late at night or in the early morning. Think of green lights as yellow caution signals.
Travelers also say parking is near impossible in Old San Juan and that traffic in most urban areas slows to a crawl during rush hour.
In many rural areas, road signs are nonexistent, and roadways can be narrow and winding. So narrow in fact, that a two-lane road actually becomes a one-lane road. Drivers must honk to let others know they are trying to get by, especially at night and on blind turns and curves.
Recent travelers recommend using caution when driving in Isla de Vieques, as animals like horses simply roam out into the middle of the road. Whoa, Neddy.
So you've given up on driving? Though travelers say most public transportation is safe, look for taxis and buses with stickers approved by the government. This way, you can feel secure that drivers have good records and (most likely) don't intend to scam you.
Publico is a recommended shared taxi service that transports tourists cheaply to and from areas like Ponce and San Juan. You can prearrange these services or wait at a terminal.
There is also an urban train line that stops at 16 stations and 30 different bus routes. And ferry travel from San Juan and Fajardo to popular areas is also possible.
Beautiful Puerto Rico is one of the most popular destinations in the Caribbean, but there are a few things you should know before you go.
