Mrs Jean Brittain (58), who lives in Rosegrove, has also vowed to fight for better safety measures along motorways.

Harrison (14) fell into the path of a car as he crossed the fast lane in rush-hour traffic.

His grandmother said that he made a mistake and paid the "ultimate price" and now his family wants to save another family from going through the pain of losing a child.

Since Harrison's death in March last year, Mrs Brittain has met with Burnley MP Kitty Ussher who has written letters on the family's behalf to Lancashire County Council and the Highways Agency in a bid to get some form of barrier put up between Rosegrove Lane and junction 10 of the M65 to prevent access onto the motorway. This is how Harrison accessed the busy carriageway.

"This is something I feel I've got to do and I will keep on until I get something done. I am not just speaking for myself but for the whole family. We all want something to be done to stop this happening again.

"If I can just get the message across to children. Don't do it, it's not worth putting your family through.

"Anybody thinking about doing what Harrison did, please think about the consequences of your actions on your family and the families of those who could be driving. So many people are affected by it."

As a direct result of Harrison's death the Highways Agency is looking into possible action to prevent a similar tragedy, although nothing concrete has been decided.

"Children are still playing in that area. Even if they just put something up now, notices to warn children about the dangers before they build something more substantial like a wall at a later date," said Mrs Brittain.

She added that part of the reason why young people in Rosegrove hang around close to the motorway is because there is a lack of things to do in the area.

"I'm not making excuses but if only the young people had something to do round here. Harrison only went out for an hour to play football.

"He was a lovely lad and I can't understand why he did it. He made a mistake and he paid the ultimate price."

In the weeks following the death of Harrison, a pupil at Hameldon Community College, police went into schools in Burnley to warn them about the dangers of playing near the motorway.

PC Dave Bishop, of Lancashire Police's motorway unit, said: "If Harrison's death makes one person think, then it is potentially a life saved."

An inquest into his death last week gave a narrative verdict, which is where a coroner sets out all of the facts of the case.
