SAFETY campaigners are trying to save lives in Huddersfield.
Kirklees and neighbouring councils are launching a campaign aimed at getting parents to make sure their children are using seatbelts and child safety seats - as well as using their own.
Road safety officers will visit schools and nurseries to get the message across to children, their parents and carers.
Using a seatbelt or child safety seat in a car is one of the simplest and most effective ways of saving a life in a collision.
The wearing of front seatbelts became compulsory for adults in 1983 and the wearing of rear seatbelts in 1991.
But research by the Kirklees Road Safety team showed that up to three-quarters of car users are still not wearing them.
Clr Martyn Bolt, Kirklees's Cabinet member for the environment and transport, said: "All the safety devices in our vehicles are designed around the simple assumption we will be wearing our seatbelts.
"Imagine an airbag deploying at between 15 and 25 milliseconds (0.015 and 0.025 of a second) at a speed of around 180mph (290 kilometres an hour).
"Now imagine hitting that without the safety restraint of a seatbelt.
"Even at 5mph an unrestrained baby or child can be thrown forward with a force 30 to 60 times their own bodyweight, with the result that they are killed.
"Children aged under four are 10 times more likely to be killed in a car accident if unrestrained. We are simply trying to get people to think about their actions."
He added: "This campaign highlights the increased risk to yourself and your children if you don't use common sense. Use the seatbelts and child safety seats."
