A bright yellow bus visited Cardiff to help national charity Guide Dogs rev up their campaign to install audio visual (AV) technology on buses.
AV technology would see bus stops announced, so blind and partially sighted passengers could depart confidently.
The vehicle visited the city centre and Bay from Friday 12 to Sunday 14 September, providing a place to meet Guide Dogs Cymru and sign the petition.
Over 9,900 signatures were delivered to Downing Street on 2 October, 1,050 of these collected in Cardiff.
Guide Dogs Cymru engagement officer, Nathan Foy, 34, said: “I’m blind, and if a driver forgets to announce my stop, I could end up 100 yards down the road from my destination.
“If my two-year-old daughter asks: ‘Daddy, where are we?’, I can’t answer that.”
