The Government will hold a satnav summit today to try to put an end to drivers being sent the wrong way by their in-car systems.
Hosted by local transport minister Norman Baker, the summit will thrash out solutions for drivers following out-of-date directions from satnavs.
To be held at the Department for Transport headquarters in London, the summit will also look at the problem of lorries being directed down inappropriate roads.
Those attending include highway authorities, mapping providers and satnav manufacturers.
Mr Baker said: "Out-of-date directions mean misdirected traffic - a scourge of local communities.
"I am pleased that all involved have agreed to work more closely to provide drivers with accurate, up-to-date information on traffic restrictions such as narrow roads or low bridges."
He went on: "The summit will see a plan of action agreed to ensure motorists are given the best possible directions and help prevent huge lorries from being sent down narrow country lanes and through small villages.
"This is timely because from next month we are allowing local authorities to reclassify roads - ensuring A roads are placed where they want traffic to run and lowering the category of road in places they want traffic to avoid - rather than having to come to Whitehall for approval. These powers will help councils make sure that drivers are using suitable routes."
