SPEED-ACTIVATED warning signs could be introduced on a dangerous country road.
The pole-mounted electric dis-play flashes up an advisory message when it detects an oncoming motorist is travelling too quickly.
Four of them could be introduced to Old Redding, Harrow Weald, where a traffic survey revealed nine out of every 10 drivers broke the 30mph limit.
There were 26 accidents in which someone was injured between November 1, 2004 and October 30, 2007 on the rural road.
Speed cameras were rejected due to the difficulty in installing and maintaining them and the problems drivers would have in spotting them.
Paddy Lyne, chairwoman of Weald Tenants' and Residents' Association, and a former Liberal Democrat councillor, said: "It's about time. There have been numerous accidents up there - it's so dangerous.
"When I use the road I go down slowly and I have other drivers right up behind me and I have been flashed and honked at.
"Instead of going down Uxbridge Road, they use it as a shortcut to Watford or Stanmore."
The plans are currently out to consultation until July 1 and if the council is satisfied with the results, it will go ahead this year.
Four others speed-activating signs are proposed for Pinner Road, Harrow, between Bessborough Road and Headstone Lane, alongside other safety measures such as more road markings and converting Pinner View and Bedford Road into one-way streets.
These plans are also subject to consultation.
