Kapitran Andreevo is the cross-border point between Turkey and Bulgaria it is passed by E80 international road. The European roads in Bulgaria are prefixed by the letter 'E', while internal motorways and main roads are indicated by numbers only. Place names, signposted along main roads, are in both Cyrillic and Latin script (on minor roads they may be in Cyrillic only) but road signs are international. While petrol stations are found on the main road exits from most large towns and every 30-40km (18-25 miles) along the motorways, on minor roads they can be few and far between. The minimum age for driving is 18 years. The A1 and A2 are the major roads out of Sofia. The A1 heads east toward Plovdiv. The E80 from Turkey crosses the border at Kapitan Andreevo.
