” I’m driving parallel to them at 55 mph with a line of traffic behind me.”
1. If you are driving 55 and you have a line of traffic stuck behind you, you are going too slow for the highway, no matter what the posted speed is. The speed differential between you and the rest of the traffic on the freeway makes accidents *more* likely and *more* dangerous/lethal, per physics. Solution: speed up. Alternately turn your flashers on as you are a slow moving road obstruction and should designate yourself accordingly.

No. Turning on the hazard lights is illegal in many states unless the vehicle is stopped. It creates a whole new hazard in low visibility situations.
Entry to the interstate must be made at or above the speed limit
Where I live it is common to see both police and school buses doing 70 in a 55. People don’t realize that what matters is keeping up with the flow. And if a cop ever pulls you over for doing less than ten over - even in a 25 mph zone, it’s for some other reason than your speed. That is just the excuse.
