Motorists have been urged to make sure their vehicles have enough fuel and comply with height restriction before travelling through the Blackwall Tunnel, after a new report showed the busy route has been closed 1,200 times in the past nine months.
Most of the closures were due to vehicles being too high to get through or because they ran out of fuel in the tunnel, reasons that are easily avoidable.
The incidents led to 157 hours of closures and caused over 13 days of severe congestion in the past nine months, figures show.
The tunnel, which runs underneath the River Thames in London, carries around 100,000 vehicles a day.
Kulveer Ranger, the mayor ofLondon's transport adviser, said: "We all know how frustrating it is sitting in traffic, even more so when the reason for the jam is so easily avoided."
