Parking bans at two dangerous Keighley road junctions have gone “live”.
The double yellow lines were painted some time ago on West Lane and four of its approach roads.
Bradford Council has now completed the legal process that means the waiting restrictions can be enforced.
The parking ban, aimed at improving safety for both pedestrians and drivers, has been welcomed by local councillors.
Restrictions cover the junction of West Lane with Highfield Road and Guard House Road, next to Our Lady of Victories Primary School.
They also cover the nearby junction of West Lane with Back Grant Street and Devonshire Street.
John Devlin, the Our Lady of Victories head, hoped the measures would help deter parents from parking outside the school.
He said: “There’s a shocking problem with double parking and lazy parents. Some of the parents barely stop to let the children out.”
District councillor Khadim Hussain, who represents Keighley Central Ward on Bradford Council, said the yellow lines would improve safety.
He said: “By law you can’t park on corners anyway, so I don’t think this will be detrimental to residents.
“I think it will actually improve safety for residents driving into West Lane, and other people crossing the road.”
Fellow Keighley Central councillor Abid Hussain said West Lane was dangerous because people parked on both sides.
He added: “Cars come down the road at speed so it’s very difficult for people to cross.”
Coun Keith Dredge, who represents Keighley West ward, said the measures would have a positive effect on safety, adding: “West Lane is used as a rat run.”
A spokesman for Bradford Council’s traffic and highways department said the waiting restrictions were part of a 2010/11 scheme to reduce accidents.
The spokesman said: “The Traffic Regulation Order was installed to complement the main scheme, which was the introduction of a pedestrian island at the junction of West Lane/Highfield Road/Guard House Road, and a build-out at the junction of West Lane and Devonshire Street to stop vehicles cutting the corner.”
