The Buddhist flag is a modern creation it was jointly designed by Mr J.R. de Silva and Colonel Henry S. Olcott to mark the revival of Buddhism in Ceylon in 1880. It was accepted as the International Buddhist Flag by the 1952 World Buddhist Congress.
The OP seems to be asking if an ambulance if it otherwise obeys every traffic law can be cited if their ONLY offense is speeding. More specifically it seems to be saying they are only allowed to exceed the speed limit by 10 mph. At least according to Michigan, Washington and Arizona the answer to this is no.
See also the keep right law list. Many states have laws requiring vehicles to slow to 20 MPH below the speed limit when passing a stopped emergency vehicle; see the shadomoon2000 and acambre move over law lists (external sites).
