A HEARTBROKEN mother has vowed to do all she can to change Scotland's driving laws so no other family has to endure the pain of losing a loved one to an elderly motorist.

Shanneal Herron said she is determined to ensure that elderly drivers have to sit a competency test to try and prevent road deaths, following the tragic passing of her daughter Eilish Herron.

And Shanneal said the decision to tell drivers when they can no longer get behind the wheel should lie solely with the Driver and Vehicle Licensing Agency, not loved ones or GPs.

The 47-year-old said she was spurred on to launch the campaign this week, after 83-year-old Alexander Wotherspoon was found guilty of causing her daughter's death by careless driving.

Wotherspoon reversed over 17-year-old Eilish - a keen netball player and coach who was crowned Renfrewshire’s Young Sportsperson of the Year in 2013 - on September 10, 2014.

He struck the pretty teen with his silver Ford Focus, which had been adapted to be controlled with hand levers, as she was filling her blue Renault Clio up with petrol at the Asda filling station in Linwood, Renfrewshire.

Wotherspoon admitted failing to keep control of his car and, while it was reversing, hitting Eilish's car, knocking her to the ground, moving her car out of the way, reversing over her, dragging her underneath the car and causing her to be so severely injured that she died.

But he denied he caused her death by driving without due care and attention, in breach of Section 2B of the Road Traffic Act 1988, and went on trial at Paisley Sheriff Court.

He claimed, through defence solicitor Laura Irvine, that his right knee had hit a poorly installed hand lever next to his steering wheel, causing his car to shoot back and hit Eilish.

But a jury took just an hour to reject his version of events and find him guilty of the charge against him.

And, speaking after he was convicted, Shanneal said she was going to start a campaign to try and prevent others from suffering the same tragic fate as her daughter.

She explained: "Now I've got this guilty verdict I will be looking for the law to be changed.

"There should be mandatory testing for elderly drivers.

"I'm not saying 80-year-olds shouldn't be driving - an 80-year-old might be a better driver than a 30-year-old - but they should all be tested individually.

"If someone thinks they're competent, regardless of age, then let's to a test to see.

"It would be better if the decision on whether or not someone can drive lay solely with the DVLA.

"It is quite hard for a family to say to a loved one they can no longer drive.

"Now we have the guilty verdict I'm hoping this will never ever happens to anyone else's family.

"We know it will, but this gives me some amount of ammunition to try and get a campaign going."

Shanneal also hit out at Wotherspoon, over the death of Eilish, who was pronounced dead at the scene after her body was removed from under Wotherspoon's car.

The distraught mum said he had never apologised for what he had done - and said he actually stepped over her dead daughter's body after killing her.

She said: "All I ever wanted was for him to put his hands up and admit his guilt and say sorry.

"He has shown no remorse.

"He actually stepped over Eilish, my daughter's body, to get out of his car, and said he was not guilty.

"He doesn't have a conscience."

Eilish, of Paisley, was a keen netball player who played for Paisley Juniors, volunteered as a junior coach and was due to start a nursing degree.

After her death Netball Scotland created the The Eilish Herron Young Coach of the Year Award, which will continue as a yearly recognition award for young coaches of the future.

Wotherspoon, of Houston, Renfrewshire, has been banned from driving and is set to learn his fate next month.
