Did you know?

Motorists who are captured by mobile or fixed safety cameras exceeding a 30mph speed limit often claim that there were no speed limit signs on the streetlights.

We want to tell those motorists and you that 'streetlights mean 30 unless otherwise stated'.

In Wales in 2011 118,820 motorists were captured exceeding a 30mph speed limit. That is 118,820 motorists who have endangered the lives of themselves and other road users. From January 2008 to December 2010 612 pedestrians were killed or seriously injured in a 30mph limit in Wales; 200 of those were children under the age of 16.

These statistics show that it is crucially important motorists comply with speed limits. Street lights mean 30 unless otherwise stated. Many motorists are unaware of the road's speed limit. Some also claim that they weren't aware that a road was a 30mph limit as no speed limit signs were present. If you see streetlights then it means 30 unless otherwise stated.
