The mum of a teenager killed alongside her boyfriend in a horror car crash has begged drivers not to speed - as it tears families apart.

Jane Gilbert, 16, and Graham Mathie, 21, both died when his Mitsubishi Evolution hit a wall in South Lanarkshire in 2013.

Known locally as Park's Corner, the bend on the B7078 where the pair lost their lives is a notorious accident blackspot.

Jane's mum Beth has now spoken out about her daughter's death in a hard-hitting video for Road Safety Scotland.

She claims Graham was speeding right before the fatal crash, reports the Daily Record.

Holding back tears, Beth said: "My daughter Jane was only 16 when she was killed. She went away one night and never came back.

"Her driver was actually speeding which resulted in them going across the road and hitting a barrier and both of them were killed instantly."

"Jane was my one and only child. She was my only family. You never, ever dream of thinking that you're going to lose your child.

"You always think that you're going to go before them. She had a bright future."

Beth pleaded with motorists to watch their speed and described the enduring pain Jane's death left behind.

"Please watch your speed, no matter where or when, just watch your speed," she added.

"Because it does kill and it really does tear families apart."

Also in the car at the time of the crash was Graham's younger brother, Scott, who was left with serious brain injuries.

Tragically, a crash in the same spot in 2011 killed Graham's older brother, Lee Stewart, 20.

Lee was driving his brother and two other 19-year-olds when he lost control of his car.

Graham's dad, Tom Stewart, demanded action in the wake of the second crash.

At the time Tom, 44, said: “I lost both my sons that night.

"Scott has very little movement at all and cannot speak but he can communicate with us using his eyes.

“The crash happened two years and six days after my son died.

"It is well-known in the area for being an accident blackspot and the road is really dangerous.

“There are a lot of folk getting angry about this and something has to be done about it."
