Concerns over road safety for children were raised after two accidents in Huddersfield involving youngsters.
Both youngsters were hurt in the space of a few hours on Tuesday, in Honley and in Meltham.
Now many people have taken to social media to voice fears that parents and schools could do more over safety.
Many have said that more can be done with TV and council campaigns.
But officers from Kirklees Rural Neighbourhood Police responded with a message on Facebook.
They said: “We showed some of the safety films last week at a Road Safety Day at Scissett First School, the kids loved them and reacted really well to them.
“Unfortunately, the department that made all those fab Public Information Films has closed, and the Department of Transport who now produces Road Safety adverts has had their budgets slashed.
“Best thing Parents can do is try and find the old adverts on You Tube!”
Police were called to Helme Lane, Meltham, at 6.57pm on Tuesday to a report of a road traffic collision between a boy and a Vauxhall Insignia car.
The 11-year-old suffered non-life threatening wounds to his head and was taken by ambulance to Huddersfield Royal Infirmary.
He was detained overnight for precautionary checks.
Four hours earlier, a 12-year-old girl sufefred serious injuries in Honley.
She was in collision with a car in Woodhead Road and was flown by the Yorkshrie Air Ambulance to Leeds General Infirmary with injuries described as “serious”.
Police have appealed for witnesses to the accvident.
