Cam Ranh International Airport Car Rentals: Best Rates & Zero Hidden Fees

You'll need an International Driving Permit (IDP) alongside your US license—Vietnamese traffic police rarely accept a US license alone. Rent an IDP from AAA before departure ($20, valid 1 year). Without it, you risk fines of 500,000–1,000,000 VND ($20–$40) or vehicle impoundment. Some rental agencies may let you drive with just a US license, but it's legally risky.

Most agencies require drivers to be at least 21–23 years old for cars (25 for SUVs and minivans). If you're under 25, expect a 'young driver surcharge' of $10–$15 per day on top of the base rate. Some agencies charge up to $25/day for drivers under 21. Budget accordingly—this fee can add $300–$500 to a week-long rental.

Vietnamese traffic is radically different—expect swarms of motorcycles weaving between cars, minimal lane discipline, and frequent honking. Nha Trang's streets are narrower than US roads, and right turns on red are not permitted. Drivers frequently use horns to signal presence, not anger. Defensive driving is essential: stay alert, drive slowly, and avoid peak hours (7–9 AM, 5–7 PM) if possible.

unleaded gasoline (RON 92 and RON 95) is widely available at stations along the main roads. Most rentals use a 'full-to-full' policy: you receive the car with a full tank and must return it full to avoid refueling charges at $3–$5 per liter (higher than pump prices). Gas stations are plentiful on Highway 1 and the coastal road, but can be sparse in mountainous areas like the road to Dalat.

Avoid September–December—the rainy season brings flash floods, reduced visibility, and slick roads. August is the hottest month (up to 35°C/95°F), making mountain drives to Dalat physically demanding with limited AC in budget vehicles. The best driving months are January–March: dry weather, temperatures around 25–28°C, and clear coastal road views.

Toll fees on Vietnam's expressways range from 40,000–150,000 VND ($1.60–$6) per segment, payable in cash (VND) at toll booths—electronic tags are rare outside major highways. Street parking in central Nha Trang costs 15,000–30,000 VND ($0.60–$1.20) per hour; watch for yellow curbside zones where parking is prohibited. Unattended motorbikes are common targets for theft; never leave valuables visible in your car.
