Passing in the right lane and reversing on the autobahn are illegal. If you miss an exit, continue on to the next one. Many small German villages are old and picturesque, and the streets in the villages are narrow and often rough. Delivery trucks and parked vehicles will often turn these narrow streets into one-lane roads. Because of the lack of parking spaces in most villages, you can expect to encounter vehicles parked on the streets.
Farm tractors are a common sight on rural roads.
There is no law in Germany that allows a person to refuse a blood alcohol test. German police have the authority to use whatever force is necessary to obtain a blood sample. The blood alcohol limit is 0.8 parts per thousand. Most Europeans use bus transportation. When buses enter the roadway from a bus stop, the operator signals and pulls out.
