The first sentence "Ambulances in the USA have to follow traffic laws" is certainly true, although the way it's written, it sounds like it means "all of the same traffic laws as everyone else", which is not true. For example, the requirement for ambulances at traffic lights is that they be careful not to endanger anyone. But they do have their own minimal traffic laws to follow. But yes, the rest of Luc S's comment is just wrong. The law explicitly states that you must immediately yield the right of way to an emergency vehicle with flashing lights. It's not demanded; it's absolutely required. And the thing about "significant liabilities" is irrelevant, regardless of whether it's true. The simple fact is that a sirens-on ambulance does not have a speed limit to obey.
