Due to technical and economical problems the complete lighting of the rural motorway itself (i. e. excluding the access roads and the lighted signals) are switched off in Belgium at night in Belgium, but not in case of bad weather etc. The present trend in Belgium in lighting of rural motorways is to maintain the CIE recommendations of 2 cd /m as the base for the rating of the installation, but also to look to possible applications of telecontrol and electronic devices.
