Lothian and Borders Safety Camera Partnership has launched a campaign reminding motorists that streetlights mean 30mph.
The partnership has created an advertising campaign and postcards informing motorists that if they see streetlights they should presume the speed limit is 30mph.
The advertisements will be located on petrol pumps in the area and the postcards will be distributed to businesses.
The Highway Code states streetlights mean 30mph unless signed otherwise; an area with a 20mph or 40 mph speed limit will have signs alerting drivers to the fact.
Victoria Edmond, Lothian and Borders Safety Camera communication officer, said: “Unfortunately, many people do not realise that streetlights mean 30mph.
“Often I hear people say ‘the road wasn’t residential so it can’t be a 30mph speed limit’. I would ask people not to think residential means 30mph but that streetlights do mean 30mph.”
