Trivandrum International Airport Car Rentals: Best Rates & Zero Hidden Fees

Yes, an International Driving Permit (IDP) is mandatory. Your US driver's license alone is not valid in India. You must carry both your US license and IDP when driving. Get your IDP from AAA before departure (about $20). Rental companies rarely accept US licenses without IDP. Minimum driving age is 18, but many agencies require 21+ for car rentals, with a young driver surcharge of 300–500 INR/day if under 25.

Very challenging initially. Kerala uses left-hand traffic (vehicles drive on the left side, driver sits on the right). US tourists must override years of right-side driving habits. Roundabouts follow British-style left-hand priority. The first 2–3 hours are the most dangerous—stay alert, drive slowly, and avoid peak traffic. Consider hiring a local driver for the first day if possible.

Not recommended for inexperienced drivers. Monsoon runs June–November, bringing intense rainfall, severe flooding in low-lying areas, and frequent landslides on hilly roads around Thiruvananthapuram. Visibility drops drastically, and potholes hide under standing water. If you must drive during monsoon, verify your rental includes flood damage coverage and avoid mountain roads after heavy rain.

Petrol and diesel are standard in Kerala. Petrol is the primary fuel for most rental cars. Gas stations are abundant in city areas but can be spaced 20–30 km apart in rural zones. Most rentals operate on a full-to-full policy—return empty and you'll pay for refilling at local pump rates (typically 100–120 INR/liter for petrol). Electric vehicle charging infrastructure is virtually nonexistent outside major cities.

Horn honking is constant and signals 'I'm here' rather than anger. Expect vehicles to overtake from both sides simultaneously. Auto-rickshaws cut across lanes unpredictably. Traffic lights are often treated as suggestions rather than rules. Speed bumps (sleeping policemen) appear suddenly without warning. Keep windows down in heavy traffic to hear motorcycles approaching. Parking costs 20–50 INR/hour in busy areas.
