Description
The chariot was an open vehicle with two or four wheels, used in war or for traveling. War chariots were at first heavy, made of wood, with solid wooden wheels. In later biblical times, they were constructed with a light wooden frame with a standing platform and two wheels set toward the back of the frame. The wheels were a rim with four or six spokes and were set wide apart (about twice the width of the chariot frame) to give extra mobility. The wooden frame was sometimes covered with leather. A pole extended from the center of the front of the frame, and to its end were yoked animals to pull it. It was about 2.5 meters (8 feet) long.
Usage

Chariots were also used as a form of transportation, primarily by wealthier people.
Translation
In languages that have no technical term for “chariot,” it is possible to speak of a war chariot as “war carriage,” “horse-drawn war cart,” “war cart pulled by horses,” or “horse-drawn cart for fighting.” A traveling chariot, such as the one mentioned in ACT 8:29, may be rendered “traveling carriage” or “horse-drawn vehicle.”
In SNG 3:10 the Hebrew word merkav indicates the fancy “bench” or “seat” on which the honored chariot rider sat. For the same word at LEV 15:9, see Saddle, saddle cloth.
