One hundred ambulances run by the service that covers Hampshire and Berkshire are now displaying poppy stickers ahead of Remembrance Sunday.
South Central Ambulance Service says they've already had positive feedback from people who've seen them on the road.
The stickers will stay on the ambulances throughout November.
Assistant Director of Operations at SCAS and Army Reservist, Paul Jefferies, said, “I am delighted that staff across our organisation will be able to use these vehicles to help commemorate a landmark occasion that touched the lives of so many people in our region.
"Feedback from those who saw the first poppy branded vehicle roll out into active service was overwhelmingly positive and I’m sure our staff will be extremely proud when using these vehicles."
