POLICE have launched a road safety campaign targeting a "treacherous" stretch of the A38, which has claimed several lives.
There have been a number of fatal collisions along the A38 between Plymouth to Liskeard, including a crash which killed 19-year-old motorcyclist Adam Smart in June last year.
In November Lee Skeldon, 27, and Christopher Williams, 21, lost their lives near Whity Cross, Saltash, when their car travelled across the carriageway and hit a wall.
This month police will promote safer driving and will aim to reduce casualties by enforcing speed restrictions and police patrols.
Inspector Dan Ivey, responsible for policing in the South East Cornwall area, said: "Statistically, this stretch of road has a number of serious injury and fatal road traffic collisions.
"The speed restriction for the parts of the road which extend to a dual carriageway is 50mph and it is very clearly signposted as such.
"Drivers are regularly ignoring this, overtaking and speeding way in excess of this restriction, even crossing onto the protective hatch markings or crossing double white lines to overtake."
Police have described the stretch of the A38 between Trerulefoot and the Tamar Bridge as "treacherous".
The police have pledged to get more officers onto the roads to tackle the fatal four – inappropriate speed, intoxication, driver distraction and failing to wear seatbelts.
There were almost 120 accidents on the A38 in 2012, the most recent year for which figures are currently available.
There are also higher numbers of accidents at junctions around Plympton and towards South Brent.
The majority of accidents involve one or two vehicles, but there were two multivehicle pile-ups involving five vehicles and three involving four.
Mr Ivey said an officer stood near Stoketon Cross with a handheld speed detection device that caught six drivers in just one hour travelling at between 65 to 77mph – in a 50mph zone.
He said: "The sections of dual carriageway on the winding stretch of this route are designed for overtaking slow-moving heavy goods and agricultural-type vehicles.
"We have witnessed people driving way in excess of the 50mph restriction, recently in strong winds and driving rain, and in circumstances which place themselves and other road-users in significant danger."
