Drivers and passengers are being warned of the dangers of not wearing a seat belt as part of a new police campaign.
The two-week campaign will look to raise awareness and call on people to ensure they are fastened up when making a journey in a vehicle.
Some 20 per cent of all fatal road traffic collisions involve someone not wearing a seat belt, with figures rising to 25 per cent of all men killed on the roads in the UK not wearing a seat belt.
During last year’s national campaign, 5,361 people were stopped – with 4,345 prosecuted for not wearing a seat belt.
Inspector Greg Hunt, who leads Derbyshire Constabulary's roads policing teams, said: “There are not many times that you can say that a simple two second act can save your life – but with seat belts that is the reality.
"We see on an all too regular basis the devastating impact of not taking those few seconds at the start of a journey.
"There have been examples in our county where people who were not wearing a seatbelt have died in collisions where their fellow passengers, who were wearing them, have not – it really is that black and white."
A driver or adult passenger caught without a seat belt on can receive a fine of up to £500.
If you are the driver of a car with children as passengers, you must ensure they are sitting in car seats appropriate for their age and height - you are liable for a fine if they are not.
Derbyshire Fire and Rescue Group Manager, Kevin Page, said: "The simple act of putting on a seatbelt can make the difference between life and death, the difference between families’ lives being torn apart and love ones being lost forever, something that sadly our firefighters see on a regular basis on roads across Derbyshire.
"It only takes two seconds to put a seatbelt on and this could be the most important two seconds of your journey."
This year’s campaign will begin on Monday 29 June and run until Sunday 12 July.
