A MOTHER has started a petition to try to slow down traffic and add more crossings on a busy road that families cross every day. Polly Wrenn is concerned about children’s safety as Shirley Drive in Hove is a 30mph road with no crossings but is used by youngsters from a number of schools in the area. The road is a busy route out of Hove and residents said that there have been several crashes in recent years. Mrs Wrenn said on the 38degrees petitions website that there are eight pedestrian crossings from the seafront up Grand Avenue and The Drive – but none once the road becomes Shirley Drive.
