Red is historically the color of choice for U.S. fire trucks and many ambulances so much so that there’s even a popular color known as “fire engine red.” Yet red is arguably the worst choice when it comes to making emergency vehicles visible to passing motorists because “the human eye is red-blind at night,” says Stephen Solomon, OD, licensed optometrist and veteran volunteer firefighter.
Adding black chevrons and trim to the red doesn’t help the situation. “In fact, you cannot camouflage a vehicle better than to paint it red and black,” says Solomon, an expert in emergency vehicle visibility. “Red and black is completely absorbed into the background due to the way people see it, so you’ve made the vehicle practically invisible.”

Daylight Saving Time begins on Sunday, March 14.
Clocks are turned forward an hour at 2 a.m. to 3 a.m., meaning we lose an hour of sleep if we wake up to an alarm set for Sunday morning.
The benefit? Sunrise will be an hour later, just before 7 a.m. in Massachusetts, instead of around 6 a.m. As the days continue, the evenings will continue to be brighter.
