What you need to know before you drive in Costa Rica.
Costa Rica is beautiful to drive. It's also full of surprises that catch unprepared travelers off guard. I've driven every road in the country for 5 years — here's what matters.
The essential rules
Never drive at night
This is the single most important rule. Potholes are invisible. Livestock wander onto roads. Road markings disappear. Speed bumps (tumulos) are unmarked. Signage is minimal. Accidents at night are disproportionately serious. Plan every day so you arrive before dark.
Avoid afternoon drives in rainy season
May–November, the pattern is reliable: mornings are clear, afternoons bring heavy rain, sometimes with landslides on mountain roads. If you're driving Cerro de la Muerte or coastal mountain routes, do it in the morning. Arrive before 2pm and you'll be fine.
Know when you actually need a 4x4
Main routes: regular car is fine. Osa Peninsula interior: 4x4 required. Many Nicoya beach roads in wet season: 4x4. Mountain fincas: depends. I specify the exact vehicle class for your specific route — so you don't overpay for a 4x4 you don't need, or underrent one you do.
Costa Rica distances are deceptive
100km can easily take 3 hours. Mountain switchbacks, speed bumps every 2km through villages, unpaved sections, and construction slow everything down. I build realistic travel days — not what Google Maps says, but what actually works.
Fuel planning in remote areas
Gas stations are sparse in the Osa Peninsula, the Nicoya interior, and La Amistad highlands. Never start a remote drive below half a tank. These itineraries flag the last reliable fuel stop before each remote leg.
Speed bumps are everywhere — often unmarked
Tumulos (speed bumps) appear every few hundred metres through towns and villages, often unpainted and invisible at speed. The fine for hitting one too fast is your suspension. Slow before every village entrance. When in doubt, slow down.
Police checkpoints
Tráfico checkpoints are common on main highways. Have your international driver's license, passport (or copy), and car rental documents within reach. Officers are generally courteous with prepared tourists. Fines are issued on the spot for speeding.
Mountain pass road conditions
Cerro de la Muerte and the road to Monteverde can close or become dangerous with fog, landslides, or fallen trees. Check road conditions (COSEVI website or ask your lodge) before mountain crossings in rainy season.
What every driver should have
I plan the drive too
Every itinerary I build includes realistic driving days, correct vehicle recommendations, fuel stop flags, and — if you book a Custom Itinerary — my WhatsApp on your phone for the road.
