Plans to reduce speed limit on Horseshoe Pass
The speed limit at a beauty spot with a history of road crashes could be reduced from 60mph to 40mph.
Denbighshire council and North Wales Police recommended the reduction on the Horseshoe Pass following a review.
A public consultation will be launched before a final decision is made.
The stretch, on the A542, reaches a maximum height of 417m (1,367ft) and there is a steep drop on one side. It is a well-known tourist spot, also popular with motorcyclists.
In April, the road - above Llangollen - was closed after a car fell down an embankment and a man was airlifted from the scene.
At the time, North Wales AM Llyr Gruffydd said safety on the road needed to be improved, and called for safety barriers or speed restrictions.
