From 2026, trucks over 7.5 t will no longer be allowed on Route 42. Hungary redirects traffic to the M4

Hungary is introducing a ban on trucks over 7.5 tonnes on National Road 42. Transit traffic will be diverted to the M4 motorway.

Starting in 2026, vehicles with a GVW exceeding 7.5 tonnes will not be permitted to use National Road 42 on the section between Berettyóújfalu and the Romanian border. The restriction will also apply within the municipalities of Biharkeresztes and Ártánd. The Hungarian Ministry of Construction and Transport announced that heavy-goods traffic should be redirected to the M4 motorway. According to the ministry, this measure aims to reduce the burden on local communities and improve road safety.

The ban will be enforced in the same manner as other Hungarian weight restrictions, meaning carriers must expect substantial financial penalties for violations. The ministry stated that authorities will carry out intensified inspections on access roads. Transport companies are advised to take the change into account when planning transit routes toward Romania. For now, no information has been provided regarding potential exemptions for local traffic.
