Motorists across Hertfordshire are being reminded to stop whenever they are asked to do so by school crossing patrols, as part of the latest 'Stop Means Stop' campaign.

Across the county there's a network of 150 school crossing patrols on hand to help children and their parents cross busy roads before and after school.

By law, motorists are required to stop whenever the distinctive 'lollipop' sign – which is clearly marked 'Stop' – is raised.

The county council's executive member for environment, growth and transport, Cllr Paul Zukowskyj, stresses that the vast majority of motorists already comply with the signs. But he says there are still "too many" that fail to do so.

This week the countywide 'Stop Means Stop' campaign sets out to reinforce the legal and moral responsibility of drivers to stop.

As part of the campaign a number of patrols are wearing high-visibility 'Stop Means Stop' tabards, with messages being promoted across the council's social media channels.

Footage from body-worn cameras – which are routinely issued to patrols in specific locations – will capture any incidents that will be reported to the police.

"[With the campaign], we're trying to raise the profile of school crossing patrols and the dangers they face if motorists don't comply," said Cllr Zukowskyj.

"The vast majority of drivers do what they're supposed to do, but it only takes one to knock a child over.

"Our school crossing patrols do a fantastic job. And they're doing their level best to keep our kids safe.

"People need to abide by the law and stop does mean stop."

Officials say the campaign is part of a wider effort to improve road safety and to encourage 'active' travel to school, such as walking or cycling.
