The best way to explore Aruba's hidden beaches and off-the-beaten-path spots is definitely by car. The good news? Driving here is pretty straightforward. Aruba drives on the right-hand side of the road (just like the US and Canada), and while the roads are mostly paved and well-maintained, you'll encounter some bumpy stretches—especially if you venture out to more remote beaches or into Arikok National Park. A few of the really remote areas have dirt roads, so if adventure is on your agenda, consider renting a 4x4 or SUV.

Speed limits are posted in kilometers per hour, not miles, so make sure you're reading the signs correctly. In urban and residential areas, the speed limit is typically 30-40 km/h (about 18-25 mph). Out of town on main roads, it's usually 60 km/h (around 37 mph), and on the faster highways like L.G. Smith Boulevard, you can drive up to 80 km/h (about 50 mph). There are plenty of speed limit signs, especially in school zones and populated areas, so keep your eyes peeled. Aruba also has a lot of roundabouts—they might take a minute to get used to if you're not familiar with them, but just remember: traffic already in the roundabout has the right of way, and you need to yield before entering.

At intersections without traffic lights or signs, vehicles approaching from the right have the right of way. When making a left turn, you must yield to oncoming traffic. One unique thing about Aruba's gas stations—most are not self-service. An attendant will pump your gas for you, which is actually pretty nice! If you do encounter a self-service pump, you'll need to pay inside first before pumping. Also, watch out for goats and donkeys, which sometimes wander onto the roads, especially near Arikok National Park. Drive carefully on wet roads—the occasional rainfall can mix with road oil and create surprisingly slippery conditions.
