Take city bus no. Get off at the last station. The street is called Sentandrejski put. Head straight down the same road for another 15 minutes, until you reach a big intersection with the motorway. Keep walking in the same direction for another 20 minutes after the intersection, and hitchhike from there. If a car doesn't stop while you are thumbing at the intersection, you can try hitchhiking from the petrol station near the supermarket Ronda.
Use a sign "Subotica". The hitchhiking generally works better there and there's no risk of police making you problems. Get off at the last stop and hitchhike right from there, about 30 meters from the bus stop. The place doesn't look like a good hitchhiking spot, but it works fine, maybe even better than the motorway.
Get off at the last station, then walk straight ahead. After about meters you'll bump into the motorway. Head straight for Temerin and Becej, right for Belgrade wait in front of the parking adjacent to the huge gray shopping mall - Roda Megamarket. There is a big road leading to motorway to Belgrade. Take bus no. Near the town centre there's a gas station, a good hitchhiking spot. The other option is to take bus no.
There's a city bus depot there, so just hitchhike in front of it. To start off, catch bus 9A there's a bus stop right after the bridge going to the Fortress, but probably also another one within the city. Get off at the final stop, on road Then walk for 5 minutes and you will find a perfect spot with a large area for cars to stop.
You will see it anyway, because the bus passes it before turning around for the official bus stop you can try to ask the driver to let you get off while he is turning around as it will save you the 5-minute walk. Then your best shot is probably to find someone to take you to Ruma. There, you can hitch hike again at the highway toll and try to find someone to take you to Croatia. It is not an extremely busy road, but cars are going very slow since they must stop for the toll, which makes it a good spot.
