Due to the development works of the HU-GO e-toll sales system of the National Toll Payment Services Plc, the system may run slower or temporarily shut down between 17 June 2016, 6:00 pm and 19 June 2016, 04:00 am.

Due to planned maintenance works, purchases cannot be launched in the National Mobile Payment System from May 7, 2016, Saturday, 10:00 p.m. until May 8, Sunday, 03:00 a.m., so mobile parking, which is unified throughout the country, will not operate, and e-vignettes and HU-GO route tickets, which are related to motorway use and which can be purchased via mobile payment, will not be available.
