Hundreds of police officers were sent to notorious London junctions this morning in a bid to cut the "appalling number" of people killed commuting around the city.
The Met Police said around 2,500 officers will be involved in Operation Safeway in an "effort to make all road users safer by robustly enforcing the law and educating them about dangers".
The operation comes in the wake of six cyclists' deaths in a two-week period earlier this month. Last week, Metropolitan Police Commissoner Sir Bernard Hogan-Howe, said he would not cycle in London over safety fears.
The Met said officers will "police key junctions across London during morning and afternoon rush hours, where they will issue fixed penalty notices to people who commit traffic offences. Officers from other policing teams will also be keeping an eye out for anyone who commits an offence on the road during their day-to-day duties, and taking action."
Police will also be offering safety advice to road users
Operations lead Superintendent Rob Revill of the Safer Transport Command, said: "Our aim is to reduce the appalling number of people who die or are injured on London's roads each year. Every road death is a needless tragedy that wreaks devastation for the victim's friends and family. Every serious injury is life-changing and distressing."
A total of 166 junctions with the highest collision rates will have a police presence during the operation, said the Met.
Fourteen cyclists have died in London this year. Nine involved heavy goods vehicles.
