Slovenia boasts a well-developed motorway network with four major routes, including the essential A1. These motorways are seamlessly connected to regional roads, providing drivers with comprehensive access across Slovenia. To use this network, a digital toll sticker, known as a vignette, is required. Vignettes are available for various time periods and can be easily purchased online from our site E-Vignette Slovenia, as well as at service stations and post offices.
The construction of the A1 highway started in the 1970s, originally linking Slovenia's capital, Ljubljana, to the coastal port of Koper. Over the years, the A1 has expanded northeast of Ljubljana, undergoing numerous upgrades to support increasing traffic demands. Since Slovenia gained independence, substantial investments have transformed the A1 into a modern and advanced transportation corridor.
As for the tolling system:
- Pre-2008: Drivers had to pay tolls at tollbooths along the motorway.
- 2008 Onwards: A vignette system was implemented for vehicles under 3.5 tons.
- Heavier vehicles still pay tolls at booths.exclamation Tollbooths are being reorganized to allow vignette holders a smoother passage.
