1. Ambulances were first used on battlefields. They were carts that took wounded soldiers to
field hospitals. These horse-drawn ambulances were common in Europe and North America in the 19th century.

2. The world’s first motorized ambulance was commissioned by the Michael Reese Hospital in Chicago and hit the streets in February 1899. It was powered by an electric motor.

3. The largest ambulance is operated by the Dubai Government’s Centre of Ambulance Services. it measures 65.71 feet and can transport 123 patients and medical staff.

4. At first, until about the middle of the 20th Century, most ambulance services were provided by funeral homes, because regular passenger cars couldn't fit a person lying flat on a stretcher.

5. If you look in your rearview mirror, the word AMBULANCE on the front of the vehicle reads perfectly. It is intentionally printed backward—a technique known as Ambulance Ambigram or mirror writing. This allows drivers ahead to glance in their mirrors and instantly identify the emergency vehicle behind them without a second thought.

6. Sirens are multi-tonal for a reason. Ambulance sirens do not just make one continuous sound; they switch between different modes depending on the traffic situation: The Wail: A long, slow up-and-down sound used primarily on open roads or highways to warn traffic far ahead. The Yelp: A rapid, frantic sound used at busy intersections to signal immediate urgency. The Rumbler: A relatively modern innovation that emits low-frequency sound waves. This creates a physical vibration that drivers can actually feel inside their vehicles, which is incredibly useful for getting the attention of distracted drivers listening to loud music.

7. The term ambulance comes from the Latin word ambulare, which means "to walk" or "move about." The term was first formalized by Baron Dominique-Jean Larrey, Napoleon Bonaparte’s chief physician. He created the ambulances volantes ("flying ambulances")—fast, horse-drawn carriages designed to quickly move wounded soldiers off the battlefield to receive medical care, rather than leaving them until the fighting ended.
