A new report commissioned for the Government has found that the 'rush hour' for drivers using the M25 can actually last from 6am to 6pm.
The finding is a surprising one to many, but some transport campaigners say that people who use the M25 already know that there is a lot of traffic on the route.
The Department for Transport says that it is spending a lot of money on improving the south's major routes.
“We are investing £15 billion up to 2020 delivering upgrades to motorways and major A-roads.
“We continue to work on ways to cut congestion and improve journey times on the M25, connecting people with jobs, leisure and culture venues in the area – and providing an important boost to the UK economy.”
