Deputies in Pasco County, Florida, posted photos to Facebook of the (pre)historic traffic stop.
Officers had a little fun with a man, who was dressed like the classic cartoon character riding the footmobile.
"Mr. Flinstone was issued a citation for speed and became unruly and had to be detained," police said. "After further investigation, Mr. Flinstone was issued a Notice To Appear and released."
The sheriff's office joked the vehicle is now part of the Pasco Sheriff's office fleet.
Authorities were sending a message with these staged photos to anyone thinking of speeding in the area.
They thanked Mr. Flintstone and his wife, identified as Don and Trina Swartz, for "being such great sports... Yabba Dabba Doo!"
