Driving Rules and Guides in Czech Republic:
◾ Right-Side Driving
As with most European countries, the Czech Republic follows right-hand driving. Always drive on the right side of the road and overtake from the left.
◾ Use of Horn in Prague
Within the city limits of Prague, the use of a car horn is prohibited unless it's to avert an immediate danger. Stay alert and be respectful of this rule to avoid fines.
◾ Parking
Blue zones denote short-term paid parking areas. To park here, you'll need a parking ticket, which can be purchased from nearby machines. Make sure to display the ticket visibly on your dashboard.
◾ Speed Limits
Urban areas have a speed limit of 50 km/h, while outside towns it's typically 90 km/h. On expressways, it's 110 km/h, and on motorways, you can go up to 130 km/h.
◾ Documentation
Always keep your driver's license, car rental documents, passport, and the vehicle's "green card" (proof of insurance) on hand when driving.
◾ Crossing Borders
If you plan to take your rental car outside the Czech Republic to neighboring countries, ensure you inform your rental agency in advance. They can provide you with the required documentation and inform you of any restrictions. Remember that insurance policies might change or might not be valid once you cross borders, so always stay informed.
