Speed cameras have been fitted along part of a busy rural road in Norfolk in a bid to prevent collisions.
The A149 from Potter Heigham to Cats Corner in Stalham has a speed limit of 60mph, with sections at 50mph.
Norfolk County Council said that even with mobile safety camera checks some motorists put other road users at risk by driving too fast.
The Department of Transport and the council has funded seven average speed monitors along the five-mile section.
Carol Croft, who has lived next to the road for 25 years, told BBC Radio Norfolk that she had witnessed and helped victims of several crashes and hoped the cameras would make the road safer.
She said: "I have seen a number of fatal accidents since living here and hopefully we won't have any more.
"It is quite frightening and it makes you think twice about sometimes pulling out of the junction, and particularly for motorbikes."
