When selecting insurance, consider whether it includes free excess coverage. Free excess means you won’t pay a deductible in case of damage, providing additional peace of mind. Compare options to find the best fit for your needs.

Research any toll roads on your travel route and understand the payment options. Some rental companies provide toll transponders for convenience.

If you're looking for extra comfort or features, ask about upgrade options at the rental counter. Often, discounted upgrades are available at pickup.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.
