My first afternoon in Oman, I rented a dusty 4WD to explore the towering sand dunes of Wahiba Sands. When I finally drove back into Muscat, my vehicle was completely caked in fine, orange desert dust. I pulled up at a stoplight next to a police cruiser, only to have the officer politely pull me over. He wasn’t checking my speed; he was pointing out that my car was far too dusty and that I was facing a 10-Rial fine. It was my first introduction to Oman’s strict public cleanliness rules.
Oman is a stunningly beautiful country where dramatic wadis, empty deserts, and ancient forts meet a highly structured, modern society. But if you aren’t careful, you can easily end up with a traffic fine, a rejected booking, or get turned away from a landmark. Here are 5 weird, quirky, and freshly updated things you must know before traveling to Oman in 2026.
1. The 10-Rial “Dirty Car” Fine
Can you really get fined for having a dirty car in Oman? Yes, the Royal Oman Police (ROP) actively issues fines of 10 Omani Rials (roughly $26 USD) to drivers of vehicles covered in excessive dust, mud, or grime. The regulation is designed to preserve the clean, aesthetic appearance of the country’s public roads.
During my trip, I learned that this rule is especially strict when dust or mud covers your vehicle’s license plates, making the numbers unreadable. For travelers renting a 4WD to explore off-road destinations like Jebel Akhdar or Wadi Shab, this is a major trap. The moment you return to paved highway roads or enter city limits, you need to head straight to a local car wash (known as a maghsala) to clean the exterior of your vehicle. You can easily find them at major petrol stations like Shell or Omanoil, and a quick wash only costs about 1.5 OMR.
Pro-Tip: Don’t try to save money by doing a quick bucket wash on the street. Washing your car in public residential areas or on street curbs is also illegal in Oman and carries a 10-Rial fine. Stick to the commercial car wash bays.
2. Cash-Only Souqs and the DCC Exchange Rate Trap
Can you pay with a credit card everywhere in Oman? No, you cannot rely solely on cards or mobile wallets when traveling in Oman. While digital payments (including Apple Pay and Google Pay) are standard in Muscat’s malls, upscale restaurants, and modern supermarkets, you must carry physical cash (Omani Rials) for traditional souqs, street food, and outdoor activities.
For instance, when shopping for frankincense or silver at the famous Mutrah Souq in Muscat, vendors will expect cash, and you’ll have much better bargaining power with banknotes. Additionally, hiring local guides to navigate the deep pools of Wadi Shab or renting a boat at Bandar Khayran requires cash payments. When withdrawing money from local ATMs or paying with a foreign card at hotel desks, the terminal will often detect your card and ask if you want to be billed in your home currency (like USD or EUR) or local currency (OMR).
Always select **local currency (OMR)**. Choosing your home currency triggers Dynamic Currency Conversion (DCC), allowing the local merchant’s bank to set a terrible exchange rate that adds a hidden fee of 5% to 10% to your bill. Selecting OMR ensures the conversion is handled by your own card issuer at the official market rate.
Blogger Tip: Travel forums on TripAdvisor suggest carrying small denomination notes (like 1 OMR, 500 baisa, and 100 baisa bills). Many small shop owners and taxi drivers do not carry change for larger 20 OMR or 50 OMR notes, so break your larger bills at airport shops or hotels.
3. Mwasalat Sayir QR Wallets and the Otaxi Card Glitch
What is the best way to get around Muscat if you don’t rent a car? Since Oman has no passenger rail system or subway networks, you will need to rely on the Mwasalat public bus network and local ride-hailing applications.
Mwasalat operates a fleet of modern, air-conditioned buses across Muscat and intercity routes to cities like Nizwa and Salalah. To ride, they recommend cashless ticketing using their **Sayir e-Wallet** on the Mwasalat app. You top up the wallet using your credit card, which generates a dynamic QR code on your phone that you scan at the reader when boarding and exiting the bus. For taxis, you should avoid hailing random cars on the street, as they are unmetered and drivers often overcharge tourists. Instead, download **Otaxi**, the registered local ride-hailing app, which calculates fares transparently based on meters.
However, many travelers on Reddit have noted that Otaxi’s in-app payment system frequently glitches when processing international credit cards, resulting in failed transactions. To avoid being stuck, register your card but always keep enough cash (OMR) in your pocket to pay the driver directly at the end of the trip.
4. The Mosque Gate Wardrobe Check
Can tourists wear whatever they want when visiting Oman’s landmarks? No, Oman is a conservative Muslim country, and strict dress codes are enforced, particularly at religious sites like the magnificent Sultan Qaboos Grand Mosque in Muscat.
If you plan to visit the Grand Mosque (which is open to non-Muslims from 8:00 AM to 11:00 AM, Saturday through Thursday), you must dress appropriately, or security guards will turn you away at the gate. You can double-check visiting hours and guidelines on the official Ministry of Tourism (Experience Oman) portal. Women must wear loose-fitting clothing that covers the body completely from the wrists to the ankles. A headscarf (known locally as a shayla) is mandatory and must cover all hair and the neck. Men must wear long trousers and a shirt with at least short sleeves; shorts, tank tops, and sleeveless shirts are strictly prohibited.
Even outside the mosque—such as in shopping malls or public parks—modest clothing is expected. Wearing short shorts or sleeveless tops in government offices or public markets is considered disrespectful and can lead to confrontation or refusal of service.
5. Swearing, Rude Gestures, and Photo Privacy Laws
Is public behavior closely monitored in Oman? Yes, the Omani Penal Code takes public conduct and respect very seriously, and certain actions that might be ignored in the West can carry severe legal consequences.
Public swearing, shouting, or making rude hand gestures (especially while driving in traffic) is treated as an offense against public decency. If a local reports you to the police for swearing or making offensive gestures, you can face arrest, heavy fines, or even deportation. Additionally, privacy laws are strictly enforced. Taking photos of local people—especially Omani women—without their explicit, prior consent is illegal and considered a serious insult. You must also avoid photographing military bases, police stations, government offices, and border crossings, as doing so can lead to immediate questioning and confiscation of your camera equipment.
Pro-Tip: When taking travel photos in public spaces, keep your camera pointed at the architecture or landscape. If locals are in the frame, it is best to ask for permission or frame the shot to keep their faces obscured.
Bonus: Karak Tea and Omani Halwa
If you want to experience authentic Omani hospitality, find a small local coffee shop and order a cup of **Karak tea** (spiced milk tea brewed with cardamom and saffron) and a slice of **Omani Halwa**. Omani Halwa is a traditional sweet made from starch, sugar, saffron, cardamom, rosewater, and ghee, slow-cooked in large copper pots for hours. It has a sweet, aromatic, gel-like texture and is typically served with bitter cardamom-spiced coffee (Gahwa) to balance the sweetness. It’s a delicious window into the local culture that you shouldn’t miss.
