Two schools in Lichfield are among the latest to have 20mph speed limits introduced outside their gates.
St Stephens Primary in Fradley and Whittington Primary will join the 20 is Plenty initiative next term.
The schools will have speed indication devices installed as part of the project.
Cllr Mark Deaville, Staffordshire County Council’s transport chief, said: “We’re in the seventh year of the scheme now and so far over 200 schools across the county have benefited from it. The campaign calls on drivers not to put pupils lives at risk by driving above 20 miles an hour when outside schools.
“The scheme is also encouraging more parents and children to walk and cycle to school which helps to reduce traffic at school times.”
