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.
Some doctors' offices are equipped to handle overdoses; others are not. Some doctors' offices advise their patients to go to a hospital's emergency department. In life-threatening circumstances, an ambulance should usually be summoned by calling 911.You are not expected to know when a drug overdose is serious.
