Bulgaria → Serbia runs via the Kalotina–Gradina crossing on the E80/A4 motorway, the main road link from Sofia to Niš and Belgrade. Smaller crossings (Vrška Čuka, Strezimirovci) handle local traffic. Serbia is outside Schengen, so full border checks apply; queues are typically 30 minutes to 2 hours, with longer waits during diaspora summer returns and around New Year.
