The mother of a teenager severely injured in a car crash has backed Sussex Police's plans to introduce more speed cameras.

Harriett Jordan Wrench was left unconscious in a hospital bed fighting for her life after suffering a fractured skull, leg, ankle and pelvis in the accident at Christmas in Madeira Drive, Brighton.

She was unconscious for a month and also suffered broken ribs.

The 16-year-old, of Miller's Road, Brighton, was released from hospital this week.

Her mother, Pauline Jordan, said the cost of medical care, drugs and legal fees after the accident would run to seven figures.

She said more cameras and making people pay more for speeding would help prevent similar incidents in the future.

Mrs Jordan said: "Some people do not take responsibility for themselves or others.

"It is not just speed - you see it all the time with people on mobile phones.

"Anything that can help to compel people to take responsibility has to be welcomed.

"If it hits people's pockets then that's OK - they should not be speeding.

"If anyone had to look at their child in intensive care over Christmas, they would think twice about speeding."

At the moment, Sussex Police operate 13 cameras in West Sussex and 19 in East Sussex, including Brighton and Hove. More will be introduced next year.

A force spokesman said he did not know how many new cameras would be brought in but each would have to be justified on safety grounds.

Superintendent Nick Bennett, who heads Sussex Police traffic division, said new cameras would be introduced next April.

He said the force's policy was to only put the cameras on roads where excessive speed was causing accidents or was likely to.

Mr Bennett said the cameras would have to prove their worth in reducing deaths and casualties and the force was not interested in making money from them.
