blue or red lights. Green is primarily for medical transport.
Myth #4: “Green lights mean organ transplant transport.”
Sometimes, but not exclusively. Organ transport may use green lights, but so do dialysis vans, wheelchair transports, and lab couriers.
Myth #5: “If a car has a green light, it’s an emergency.”
No. Green means “non-emergency medical transport.” The patient needs to get to an appointment, but it’s not life-or-death.
Why Green Lights Matter (The Bigger Picture)
Green lights improve healthcare access without increasing emergency response strain.
The problem: Many patients need
regular medical appointments (dialysis, chemo, PT) but can’t drive themselves. They may be elderly, disabled, or too weak to use public transit.
The solution: Non-emergency medical transport (NEMT) fills this gap. Green lights alert other drivers, helping these vehicles stay on schedule.
