Renting a car in Montenegro provides the ultimate freedom to explore the majestic landscapes of the Balkan Peninsula. From navigating the hairpin turns above the breathtaking Bay of Kotor to driving through the rugged limestone peaks of Durmitor National Park, road trips present an ideal way to discover the country at your own pace.
However, before you drive away from the rental lot and set off on your journey along the Adriatic highway, you need to carefully review your contract. Understanding your car rental agreement is essential for avoiding unexpected fees and unfair damage claims. This guide lists everything you need to check for a seamless and stress-free adventure.

Top 10 Things to Check in Your Rental Agreement
1. Cost Breakdown
When you rent a car in Montenegro, understanding the total cost requires looking beyond the advertised price online. A transparent contract clearly breaks down the daily base rate alongside other standard charges. Ensure that the total amount includes mandatory fees, specifically the 21% Value Added Tax (VAT) and Premium Location Fee, if you picked up your car from an airport or other major transport hub.
You should also check driver-related costs, such as the Young Driver Surcharge for renters below 25 years old, or the Additional Driver Fee for registering an extra driver in your contract. Furthermore, look for optional equipment rentals, like child safety seats and GPS units. You can avoid these costs by bringing your own appropriate child or booster seats and using a mobile app for navigation.
2. Insurance Coverage
Insurance policies are one of the most critical sections of any car rental agreement. Aside from the mandatory Third-Party Liability (TPL), standard packages generally include basic Collision Damage Waiver (CDW) and Theft Protection (TP). However, these policies often come with a high deductible or excess amount, which typically ranges from €500 to €1,500, depending on the vehicle class.
To reduce this financial liability to zero, you can purchase a Super CDW or Excess Reduction package. Additionally, you should check if your policy excludes damage to the vehicle’s tyres, wheels, glass, mirrors, and the undercarriage. To protect these vulnerable car parts, you might need to purchase additional coverage.
3. Vehicle Condition
Before driving away from the rental lot, you should conduct a thorough inspection of the vehicle alongside a rental agent. Take time-stamped photographs and videos of the entire exterior and interior of the car, paying close attention to glass surfaces, bumper undersides, and tyre treads.
Rental contracts typically include an official vehicle condition report or diagram where every existing scratch, chip, dent, or stain must be formally documented. Ensuring that all pre-existing flaws are recorded and signed off by the rental representative protects you from being charged for damage caused by previous drivers.
4. Rental Schedule
Rental contracts operate on a 24-hour billing cycle, making timing a significant factor in overall costs. For collections, if your flight gets delayed, make sure to contact your rental provider immediately to avoid being marked as a no-show. It’s best to give them your flight details before your trip, so they can track changes and make arrangements.
For returns, check the agreement for grace periods, which typically range from 15 to 30 minutes. Exceeding this allowance can trigger a charge for an entire additional day. If you plan to pick up or drop off the vehicle outside of normal business hours, clarify the procedures and confirm whether an Out-Of-Hours Service Fee applies.
5. Cancellation Clause
Travel plans can shift, making it essential to understand the cancellation clauses outlined in your contract. Most suppliers offer flexible arrangements and refunds for cancellations made at least 24 to 48 hours before the scheduled pickup time. However, bookings made through third-party brokers or discounted pre-paid deals may have non-refundable policies.
Furthermore, you should pay close attention to clauses regarding early returns. If you choose to bring the vehicle back ahead of the drop-off schedule, most companies will not refund the unused days. Policies should also clearly state whether booking deposits are refundable in the event of severe travel delays or flight cancellations.

6. Fuel Policy
Fuel policies vary between rental agencies, making it essential to review them in your contract. Some companies offer Pre-Purchase or Same-to-Same options; however, the most economical arrangement is the Full-to-Full policy, where you receive the car with a full tank and must return it in the same state.
Remember to refuel at a nearby petrol station before dropping off your rental car and keep your printed receipt as proof of compliance. Returning a vehicle with less fuel than stipulated usually results in being charged a significantly inflated price per litre, alongside a hefty refuelling service charge.
7. Mileage Limits
When you rent a car in Montenegro to explore scenic routes, you may cover substantial distances. While many rental operators offer unlimited mileage in their standard rental agreements, some suppliers impose daily distance caps, particularly on luxury or speciality vehicles.
If your contract includes a mileage limit, such as 200 kilometres per day, any distance driven beyond the cumulative threshold will incur a per-kilometre surcharge upon return. If you intend to embark on long drives across national parks or along the coast, you should confirm that unlimited mileage is explicitly written in your rental contract.
8. Cleaning Standards
Rental providers expect vehicles to be returned in a reasonably clean state. While road dust or minor dirt from driving is acceptable as regular wear and tear, returning a car covered in heavy mud, sand, or deep upholstery stains can trigger a professional Cleaning Fee. Before drop-off, make sure to do a quick clean of the car to avoid additional charges.
Furthermore, take note that smoking is strictly prohibited in almost all rental fleets, and evidence of smoke odour or ash will result in substantial cleaning penalties. Similarly, if you plan to travel with pets, inform your provider and ensure they are secured in carriers or use seat covers to avoid pet hair removal fees.
9. Rental Restrictions
Most rental contracts in Montenegro strictly prohibit operating vehicles on unsealed roads, off-road trails, or beaches. Driving your rental car on unpaved surfaces or any restricted area fully voids your insurance, leaving you personally and financially liable for any resulting damage or towing expenses.
If you plan to visit neighbouring nations such as Croatia, Bosnia and Herzegovina, or Albania, you need to get proper documentation. Driving across international borders requires a valid Green Card alongside written permission from the agency. Crossing borders without these documents also invalidates your insurance and can result in severe fines or denial of entry at border control.
10. Roadside Assistance
Your rental contract must clearly outline the protocols for roadside assistance. In the event of a mechanical breakdown not caused by driver error, such as an engine failure or electrical fault, most providers cover the towing, recovery, and repair costs in full. However, if the issue is caused by negligence or misuse, you will likely be financially liable.
If you get in a road accident or collision, it is mandatory to obtain an official police accident report for your insurance claim. Regardless of how minor the incident may be, you must contact the local police to inspect the scene and issue the report. Failing to secure this document will result in the rental company holding you fully responsible for repair costs, regardless of your insurance coverage.
