Brian McCauley, 74, wants to know why the speed limit for Picton Road hasn't been lowered.

Mr McCauley and his wife live in Bowral and use Picton Road regularly on trips to Wollongong.

He said the recent deaths on the road should have prompted action.

``I've been reading all the articles and timelines in the news and it makes me wonder why the RTA hasn't dropped the speed limit down,'' he said.

``There is an unusual number of trucks on the road but I think speed is main thing.

``You feel as though you're in a race the minute you get on it.''

An RTA spokesman said managing speed was a key element for safe roads.

``In response to the recent crashes on Picton Road, the RTA is developing a comprehensive Picton Road Corridor Strategy to improve safety for all road users,'' he said.

``Key elements under consideration include the extensive use of safety barriers, a review of the existing speed limit and a review of all advisory signage on Picton Road.''

Mr McCauley, a retired engineer, said he had been using the road for 14 years and it just wasn't safe.

``You're aware you are in a risky situation, especially when those trucks start overtaking you,'' he said.

``The speed limit needs to be slower and they need to put big signs all along the road to let people know.''

The RTA spokesman said the NSW Government announced a $12 million program of safety improvements along the 27 kilometres of Picton Road from Mount Ousley Road to the Hume Highway interchange in February 2009.

``It is expected this strategy will be finalised within the next three months,'' he said.
