For someone taking to the road today the following warnings should be taken into account. Generally, you will most likely stick to high-speed and good quality motorways or expressways, but do remember, once you leave these roads onto old single lane roads, you will be driving amongst anything from a sports car to a tractor. This results in frustrated/impatient drivers overtaking each other at high speed and then braking sharply to avoid oncoming traffic. Be warned and keep a safe distance between you and the vehicle in front. Indeed, despite the overall road improvements, Poland is still one of Europe’s leading nations in road fatalities, statistics that will surprise few who have had the pleasure of using the roads here.
Also, beware of the hard shoulders of these roads, the vast majority of which are unlit at night. These are often used as pavements by local people who add to the Russian roulette by venturing out at night wearing their darkest clothing. Add in the odd drunk on a bike and these hard shoulders become a very real problem when facing a set of headlights bearing down on your vehicle.
For those brave enough to venture out on the road, the following information should be noted. Poland has strong drink-driving laws: 0.2‰ is the maximum blood/alcohol limit, so forget about having even a single beer. EU citizens may use their home driving licenses as long as they are valid, however citizens of countries that didn't ratify the Vienna Convention (tsk, tsk Australia and America) will find their licenses invalid (though that hasn't stopped anyone we know from driving their girlfriend's car). Carry your license and passport at all times when driving.
The speed limit is 50km/hr in cities (60km/hr between 23:00 and 05:00), 90km/hr outside urban areas, 120km/hr on dual carriageways and 140km/hr on motorways. All cars are required to carry a red warning triangle, first aid kit, replacement bulbs and a national identity sticker. A new law was introduced in April 2007 making it compulsory to have headlights switched on at all times. Car related crime is high and drivers should make use of guarded car parks where possible.
