I was blessed to survive this crash, when my cruiser was struck by 2 pickups trying to beat a red light. Drivers may not hear your siren in today's well-insulated cars, and may be too distracted to notice your emergency lights.
The surgeon later told me I would not have survived without my seatbelt and my vest (which he felt prevented already severe trauma from being far worse by spreading the impact and encasing my crushed rib cage).
Clear EVERY intersection. Wear your vest. Survive.
