Through all these years of my experience with road safety, I have come across a beautiful image with a solid and clear message in our own workplace, last year. Best thing about it, is that it was not even one of the many actions implemented by management...!
During a walk at our premises' parking, I saw a parked vehicle of an employee, with a child's drawing hanging next to the steering wheel.
It said : "Aunt-Uncle don't speed...I love you, Angela".
I was very amazed to see this and immediately took a picture. The children know the way and give the right example, we just need to listen to them and if not for us, we should be careful for them!
