Is driving in Costa Rica hard for Americans?

It's straightforward on paved main roads but demanding on gravel routes, mountain passes, and river fords. The biggest adjustments are slow winding roads, abrupt town speed-limit drops, landmark-based addresses, and avoiding night driving. Match your vehicle to your route and drive in daylight and it's very manageable.

Do I need an IDP to drive in Costa Rica?

No, it's not legally required — your valid US license is accepted for up to 90 days with a current passport entry stamp. It's still recommended at ~$20 because the IDP is a Spanish translation that makes police checkpoints and rental counters faster. Get it from AAA or AATA before you travel.

Can I turn right on a red light in Costa Rica?

No. Unlike most of the US, right-on-red is not permitted unless a sign specifically allows it. Wait for the green light.

What do I do at a police checkpoint?

Slow down and pull over where directed, stay in the car unless asked to exit, and have your passport (or stamped copy), US license, IDP, and rental contract ready. Be polite. Never pay cash on the roadside — legitimate fines come on an official boleta paid at a bank, so ask for the written citation if someone requests on-the-spot cash.

Should I drive at night in Costa Rica?

Avoid it whenever possible. Roads are often unlit, with potholes, pedestrians, cyclists, and animals, and gravel routes become disorienting in the dark. Plan drives to finish by around 5:30pm, since sunset is quick near the equator.

How do addresses work for navigation?

Costa Rica largely uses landmark-based directions like '200 meters south of the church.' Street numbers are unreliable, so use Waze (the local standard) with a dropped pin, and keep offline Google Maps as a backup where mountain signal drops.

What happens if I have an accident?

Don't move the vehicles unless there's a safety hazard, call 911, and contact the traffic police, the state insurer INS, and your rental agency (they'll provide the numbers). Photograph the scene, plates, damage, and the other driver's documents, get a copy of the official report, and don't admit fault or sign anything you can't read.

Do I need to speak Spanish to drive there?

Not really. Tourist areas have plenty of English, and your IDP handles the language barrier at checkpoints. A few phrases help: 'buenas' (hi), 'gracias' (thanks), 'lleno, por favor' (fill it up), and '¿se puede pasar?' (is the road passable?).

Driving in Costa Rica: 25 Tips for Americans

🚗Quick Answer

Driving in Costa Rica is exhilarating but genuinely different — gravel roads, river crossings, abrupt town speed drops, and addresses measured in meters from a church. These 25 tips will save you fines, a stuck rental, and a lot of surprises.

Your US license is valid for up to 90 days; an IDP isn't required but the $20 Spanish translation smooths every checkpoint.

Pre-Trip Prep (Tips 1–5)

Get your IDP first. It's not legally required in Costa Rica, but it's a $20 Spanish translation of your license that keeps checkpoints moving. Order from AAA or AATA before you fly — it can't be issued abroad.
Match the vehicle to the route. Reserve a 4WD if Monteverde, Nosara/Sámara, or the Osa Peninsula are on your list. In green season, prioritize clearance over horsepower.
Install Waze and download offline Google Maps. Waze is the Costa Rican standard (even police use it); offline maps are your backup where mountain signal drops.
Budget double the online rental quote. Mandatory SLI/TPL liability insurance is added at the counter and often doubles the teaser price. This is the law, not a scam.
Check the season and the specific roads. May–November brings afternoon rain and possible washouts; look up recent conditions for any gravel route or river ford before you go.

At the Rental Counter (Tips 6–10)

Bring your passport, not just a copy, if you can. The agency confirms your entry stamp is current; a copy of the stamped page is the minimum acceptable backup.
Present your IDP with your US license. It speeds up an agent who's never seen your state's license format.
Understand your insurance tiers before you sign. SLI/TPL is mandatory and can't be declined; CDW may be declinable if your credit card covers Costa Rica (bring proof, expect a higher deposit hold).
Photograph the car from every angle at pickup — including the roof, underbody area, windshield, and tires. Gravel roads mean pre-existing scrapes are common; document them.
Confirm what's excluded. Water and river-crossing damage is never covered, and rentals can't cross into Nicaragua or Panama. Know this before you drive off the lot.

On-Road Defensive Habits (Tips 11–15)

Watch for abrupt speed-limit drops. Entering any town on the Interamericana (Ruta 1) or Ruta 32, limits fall from 80 to 40 km/h with a radar trap waiting just past the sign.
Belt everyone and mount your phone. Seatbelt and phone tickets are ~₡232,000 (~$455) each and the easiest for an officer to spot. Set your route before you roll.
Expect the unexpected in the lane. Cyclists, scooters, pedestrians, dogs, potholes, and the occasional cow share the road. Leave a big following gap.
Let faster locals pass. On two-lane roads, Ticos overtake assertively. Hold your line, stay predictable, and don't speed up when someone passes.
Never drive after dark if you can avoid it. Unlit roads plus potholes, pedestrians, and animals make night driving the single biggest avoidable risk. Aim to arrive by 5:30pm.

Town & City Driving (Tips 16–20)

Navigate San José by landmark, not address. Costa Rican addresses are relative (“200 m south of the church, blue house”). Trust Waze and a dropped pin over a street number.
Mind San José's one-way grid and rush hour. Downtown is a maze of one-ways; traffic is heavy 7–9am and 4–6:30pm. Consider parking outside the center and walking.
Use guarded parking (parqueo) and tip the attendant. Break-ins at beaches, trailheads, and city lots are the most common tourist crime. A ₡500–₡1,000 tip buys peace of mind.
Never leave anything visible in the car. Not a phone charger, not a beach bag. Trunk it or take it with you.
Yield the way locals do at unmarked intersections. Right-of-way isn't always signed; go slowly, make eye contact, and don't assume you have priority.

Mountains, Rivers & Highways (Tips 21–25)

Walk every river ford before you drive it. Water damage is excluded from all insurance. If it's above the axle or moving fast, turn around — no photo is worth a drowned engine.
Respect one-lane bridges (puente angosto / CEDA). A CEDA sign means yield; the arrow shows who has priority. Failing to yield is both dangerous and citable.
Keep colones for Ruta 27 tolls. The San José–Caldera highway is tolled at several plazas (₡500–₡1,000 each). Keep ₡5,000 in small bills in the console; the cash lane is often faster.
Fuel up before the mountains. Stations thin out on remote routes (Monteverde, Osa). Fuel is full-service and state-priced nationwide, so just fill the tank when you see a station and say “lleno, por favor.”
Take mountain roads slowly and use low gear on descents. Fog on Ruta 32 and the Monteverde/Arenal climbs comes in fast. Ride the engine brake downhill rather than overheating the pads.

What Americans Get Wrong

There is no turn-on-red. Unlike most of the US, you may not turn right on a red light unless a sign explicitly permits it. Wait for green.
ALTO means a full stop — a rolling “California stop” at a rural junction is citable.
Distances lie. A 100 km drive can take three hours on winding mountain roads. Plan by time, not kilometers.
Gravel (lastre) is normal, not a wrong turn. Many legitimate routes to major sights are unpaved — that's why the 4WD matters.
A flashing hazard or a branch on the road ahead is a local warning of a breakdown, hazard, or checkpoint — slow down.
USD is accepted, but pay small road costs in colones. Tolls, parking tips, and fuel are cleaner in CRC; you'll get a poor rate paying those in dollars.

What to Do at a Police Checkpoint (Retén)

The Policía de Tránsito runs routine document checks (retenes) on main routes. They're normal — here's how to handle one calmly:

Slow down, pull over where directed, roll down the window, and stay in the car unless asked to step out.
Have your documents ready together: passport (or stamped copy), US license, IDP, and rental contract. The IDP is what turns a confused stop into a wave-through.
Be polite; a friendly “buenas” goes a long way. Most stops are a 60-second document glance.
Never pay cash on the roadside. Legitimate fines are written on an official boleta and paid at a bank. If someone asks for on-the-spot cash, politely request the written citation.
If you're genuinely cited, photograph the boleta so you can check it against any later rental charge.

What to Do in an Accident

Do not move the vehicles until authorities arrive — Costa Rican procedure requires the scene be documented as-is (unless there's a safety hazard).
Call 911 (the national emergency number) for police and, if needed, medical help.
Call the traffic police (Tránsito) and the state insurer INS — the rental company will give you both numbers; INS handles the mandatory liability coverage.
Notify your rental agency and follow their accident instructions to keep your coverage valid.
Photograph everything: both vehicles, plates, positions, damage, and the other driver's documents. Get a copy of the official report (parte).
Don't admit fault or sign anything you can't read. Let the official report and insurers sort out liability.
