Local people are now able to say whether or not they support the introduction of a 20mph speed limit on some of the borough’s B-roads.

If the public voice their approval in individual consultations now being carried out, they would be added to the borough-wide 20mph zone which has seen a lower limit in place in virtually every residential side street in Wandsworth since 2017.

The B-roads in question are:

These were not included when the main scheme was introduced in 2017, along with the main trunk roads that form part of Transport for London’s network of red routes.

Now after receiving a number of petitions and having carried out further traffic studies, the council will be asking local people if they support reduced speed limits in these roads.

The council’s transport spokesman Cllr Paul Ellis said lowering the limits could deliver a range of benefits.

He said: “I support this change because lower speed limits mean safer streets and this can encourage other forms of sustainable transport like cycling and walking.

“Accidents involving collisions between pedestrians and vehicles are three times less likely to be fatal if the speed of the impact is 20mph compared to 30mph.

“Research has shown that at 30mph, 55 per cent of collisions result in pedestrian fatalities while at 20mph this figure drops dramatically to just 17 per cent.

“And it could have a beneficial effect on air quality too. A study by Imperial College found that diesel vehicles with engines of between 1.4l and 2.0l produce fewer harmful emissions at 20mph than at 30mph while smaller petrol and diesel engine vehicles both generate fewer particulates when driven at this lower speed, so this proposal has the potential to bolster our efforts at improving some aspects of local air quality.

“We have already introduced a 20mph limit in all our residential streets – now it’s time to look at whether we should extend those rules to these B roads too.”

The consultations run until December 6.

Enforcement of speed limits is carried out by the Metropolitan Police, with the council working in support of their efforts. Any revenue generated by speed fines goes direct to HM Treasury not the town hall.
