By car
If your vehicle is registered and insured in an EU country you do not need a green card. Otherwise, make sure that your Green Card has an uncancelled "SRB" box. Coming in from Hungary, the Szeged/Horgos border crossing is notorious for its congestion. If crossing the border from Hungary, try the Tompa/Kelebija crossing point, about 20km west.
On the two-lane E75 between Szeged, Hungary to Novi Sad, please note that cars over-taking will often use the unofficial "middle-lane". Exercise caution and pull over to the hard shoulder on the right to let them through safely. The dual carriageway should be completed by the end of 2011 to eliminate this risk. Because of construction works, care should be taken (as of September 2010) as there are trucks leaving construction sites and entering highway at low speeds. These sections are restricted to 40km/h but drivers usually drive through those sections at full speed.
Police are generally stationed at major junctions or at underpasses to control traffic and speed. Drivers commonly warn others of a police presence by flicking the high-beams on two or three times. Police interceptors patrol all major highways. Drivers speeding and/or driving aggressively are stopped. Speeds of up to 140km/h in 120km/h zones are usually, but not always, tolerated.
