A pensioner in Cambridge is handing out free high-visibility vests to cyclists, after seeing injured people in hospital.

Janet Slade, 89, said she struggles to see people dressed in black, and that talking to drivers confirmed her suspicions that others do too.

Armed with a shopping trolley full of vests, she hands them out at shopping centres and near a hospital.

She told Cambridge News: “I went into hospital for another reason and they were saying they have wards full of people who have been in accidents.

“I hear the ambulances every day and I guessed that many of the calls out were for accidents. Then I met some ambulance crew and they said ‘yes you are right,’ so here’s the wards taken up with people who are invisible.

“I’m in my 90th year this year and I still have the advantage of age and ability, physical ability, to walk about with a shopping bag and trolley full of visibility vests and if I see a shadowy figure in black fleet before me and prop a bike against a wall, I say ‘you all in black, yes? …well nobody can see you and all the drivers complain.’”

She says she hasn’t had a bad reaction yet.

She added: “Some say ‘really, how much? I haven’t got any money now’ and I say ‘look take the so and so thing put it on, wear it: it’s a Christmas present.

“I simply go around being a busybody to people and challenge them,” she said. “I just hope to be completely logical about people’s dress code.”

The vests cost Janet £1.49 a piece, and she buys in bulk, 50 at a time.

She added that she never goes anywhere without a pair of white boots.

“If you have got white boots you can be seen on a dark rainy day, you can be seen at night and you can be seen in the early morning light,” she said.
