The minimum age to book a rental car is usually 21 years, though some companies allow drivers as young as 18 for an additional fee. Drivers under 25 may be required to pay a young driver surcharge of about €5-€15 per day.

📋 Young drivers are often restricted to smaller vehicle categories. Read the rental terms carefully before booking to confirm the required driver’s age if you need a vehicle in a specific category and are under 25.

An IDP must be accompanied by a driving license written in a non-Latin alphabet, such as Arabic, Japanese, or Cyrillic. EU licence holders are generally accepted without an additional permit.

💡 Even if not strictly required, carrying an IDP alongside a non-EU licence is inexpensive and removes any hassle at the rental counter or during a police check.

You may use a debit card to book a rental car, but most suppliers require a credit card for the security deposit. The credit card must be in the main driver’s name to process the deposit hold at pickup. Prepaid and virtual cards are rarely accepted, and a higher amount is blocked when debit card deposits are allowed.

⚠️ Check whether your travel companion can be registered as the main driver and use their card to book, in case you don’t have a personal credit card. You can be added as an additional driver in that situation.

Zagreb Airport (ZAG) is the closest airport to Karlovac, located nearly 49 km from the city centre. It serves as the ideal option for travellers flying in. They can quickly collect their vehicles from on-site suppliers before heading to Karlovac via the direct motorway. Rijeka Airport (RJK) is the second closest at around 83 km.

✅ Picking up a car at ZAG and driving straight to Karlovac is a natural and straightforward start to any visit.

Zone 2 (green) street parking offers good availability and costs €0.80/hr for the first hour. An extra €1.00 is charged for every added hour. Hotel Korana Srakovcić’s guarded on-site parking provides the most secure city centre option for overnight or multi-day stays. A daily parking card (DPK) at €13.00 covers all-day street parking in either zone.

Karlovac’s renovated old town does not have a visitor car park. Travellers can instead use Zone 1 (red) streets at the edge of the fortress grid, or Zone 2 (green) residential streets one block further out to park their vehicles. Both carry the same hourly rate. Almost all main parking options are a 5–10 minute walk from the Korzo and the main riverside promenades.

Car rentals in Croatia often include standard third-party liability as a legal requirement, along with CDW and theft protection. But an excess liability of about €1,000 to €3,000 may still stand, depending on the car type and rental company. Damage to tyres, glass, the undercarriage, and the roof is not covered by standard insurance, which is why travellers often purchase a Full Protection or Super CDW upgrade to avoid out-of-pocket expenses in case of any damage.

💡 Check what’s already covered in your existing insurance policy to avoid an unnecessary purchase. For example, itineraries restricted to well-maintained city roads might not actually need an underbody protection.

Although a grace period of 29-59 minutes is allowed by many rental companies, it’s not a standard practice for all. An extra hourly fee is often charged for returning a car after the grace period. A full-day rental may also apply for extended delays. You should call the supplier as early as possible if the car hire is expected to be returned late. A short extension without penalties is often accommodated by suppliers for early notification.

⚠️Returning significantly late without notice can trigger a full extra day charge at the walk-in (not pre-booked) rate, which is considerably higher.

Only if you’ve rented a car with a full-to-full fuel policy, which is the most commonly followed by suppliers in Croatia. You collect the car with a full tank and must return it full. The supplier will otherwise charge you for the missing fuel and an extra service fee. Return the car with the same amount of fuel you received at pickup if you opt for a same-to-same fuel policy.

Refuel at a petrol station as close to the drop-off location as possible and keep the receipt as proof of refill.

Yes. The A1 motorway passes directly through Karlovac and is a toll road. Given that Croatia does not use a vignette system, travellers can instead collect a ticket when entering a tolled motorway and pay for it on exit based on the distance travelled. Cash and card payments are accepted at all Croatian toll plazas, so no advance setup is necessary.

ℹ️ An ENC electronic transponder allows access to faster lanes, but it’s often excluded from rental deals. Paying by card at the booth is, anyway, an easier option for most short-stay visitors.

Yes. Driving a car hire to both Slovenia and Bosnia is allowed by most suppliers, but only with prior approval. Cross-border fees are approximately €20 per car for EU member states such as Slovenia, and around €50 per car for Bosnia and Herzegovina or Montenegro. A Green Card (proof of international insurance) must be obtained from the supplier before departure.

❗ Always declare your intended countries at the counter when collecting the car. Unauthorised cross-border travel can result in heavy penalties from the supplier and violate your insurance, leaving you fully responsible for any vehicle damages or third-party claims.

From 15 November to 15 April, winter tyres are a legal requirement on Croatian inland motorway routes when signs are posted. Karlovac sits in continental Croatia and experiences actual winter weather, meaning that snow and ice are common between November and March. Snow chains may also be needed when travelling to remote areas in severe conditions. Most rental suppliers fit winter tyres as standard during this period, but it’s always best to confirm when booking.

⚠️ If renting in winter, confirm with the supplier that appropriate winter tyres are already fitted. Some deals may already include them at no extra charge, but others may charge an extra €5–€10/day.
