In a special interview, we've been hearing from a mum who's calling for motorists to think before they drive, if they've taken drugs or drank alcohol.
Karen Marchant's been speaking out as part of Hampshire and Thames Valley Police's ongoing campaign, focused on urging drivers not to take risks behind the wheel.
Karen from Surrey, lost her daughter Rebecca, 15, in a drink drive collision in February 2016. Becca, as she was fondly called, had gone to stay with family friends in the New Forest when Karen received a call that would change her life forever.
On hearing her daughter had been killed she says:
“I went into complete shock my heart was racing I felt unwell, I’ve never felt those feelings before and basically in that instant my entire world came crashing down.”
“If you make a decision to drink and drive it is never an accident, it’s like playing a game of Russian roulette nine times out of ten you will probably get away with it but there is always that one chance that you won’t and it absolutely devastates lives.”
“He should never have got in that car, he should never have been allowed to get in that car. If you know somebody that drinks (and drives) then speak up as next time it could be somebody close to you.”
34 year old Alex McBride from Hordle, Hampshire, was driving the four minute journey home when he crashed his black E350 Mercedes Sport into a tree killing Becca instantly.
Rebecca was the front seat passenger but he also had his own daughter and eight-year-old niece in the back. He ran away from the scene and when arrested a few hours later was twice over the drink drive limit and had traces of cannabis in his system.
McBride was sentenced to four years and four months in prison and banned from driving for five years and two months at Bournemouth Crown Court in March 2016.
More than two years on, Karen's urging motorists who think they're under the legal limit to not even bother taking the risk, as she says the consequences are too high:
"It isn't worth the risk, the consequences are huge.
"If you're with someone who you know has been drinking, stop them, don't let them get in the car, or even report them."
