BBC London journalists are following emergency teams as they respond to incidents today.
Get ready for lots of 'killed and seriously injured' stats conflated into one figure. No need, really. The deaths stats alone are sobering enough. Roads can be dangerous places for motorists, cyclists, motorcyclists and pedestrians. HGV drivers tend to survive crashes away from motorways.
So far, there have been only minor injuries reported. A BBC reporter said a cyclist who injured an ankle should have been wearing a helmet, although there was no information given on how a cyclist should wear a helmet just above the foot.
"Debabani and James have already been called out to the scene of a collision between a car and a cyclist. The cyclist, who wasn't wearing a helmet, has a swollen and bruised ankle. James, the paramedic, says the cyclist was lucky to escape without suffering any head injuries."
A driver has smashed up a car on the A13 and lane-switchers have collided on the M4.
In Wembley, a pedestrian was hit by a bike, but it wasn't the cyclist's fault:
"Paramedics at the scene say that they have been told that a 16-year-old girl was crossing the road talking on a mobile, a cyclist gave way so that she could cross, but a van behind didn't give way, hit the bike and the bike hit the pedestrian. The girl was taken to Northwich Hospital. She did not have any physical injuries but had suffered shock."
