Youngsters from Positive Steps nursery in Maidenhead found themselves in the back of a police van last week.
The children hadn't been up to no good, but were instead learning more about the work done by Thames Valley Police to keep the streets safe.
It comes after pupils at the nursery, in Cookham Road, had expressed an interest in knowing more about what police do, prompting staff to invite officers along on Thursday, September 5.
Children were given the opportunity to explore a police van, sound the siren, and meet with two police community support officers (PCSOs), who showed off their uniform and explained more about what they do.
Nursery manager Kellie Woolley said: "[The children] were really excited and they have been talking about it for days afterwards."
