A new plan for getting children to and from school is being started by a local government in Eastern England. This could end the worries of many parents fearful for their children’s safety on the roads.
    Until now the local government has only been prepared to provide bus services for children living more than three miles from their school, or sometimes less if special reasons existed. Now it has been decided that if a group of parents ask for help in organizing transport they will be prepared to go ahead, as long as the arrangement will not lose money and children taking part will be attending their nearest school.
    The new plan is to be tried out this term for children living at Milton who attend Impington School. The local government has agreed to offer a sum of money for a bus service from Milton to Impington and back. Between 50 and 60 parents have said they would like their children to take part. A government official has said the cost to parents should be less than ￡20 a term.
    They have been able to arrange the service at a low cost because there is already an agreement with the bus company for a bus to take children who live further away to Impington. The same bus would now just make one more journey to pick up the Milton children.
