The NASA
Chariot is a lunar truck prototype created to service the future US lunar outpost. Developed by the Exploration Technology Development Program's
Human-Robotics Systems Project in just eleven months, the vehicle is designed
to meet the payload transport, range, terrain and speed specifications defined
by NASA's Lunar Architecture Team.
The Chariot's chassis can be reconfigured for a variety of
purposes and payloads. It can carry a mix of suited crew and payload; it can
also be outfitted with a small pressurized cabin.
The pilot's control pedestal can rotate 360 degrees; the
Chariot has no "front" or "rear." According to Johnson Space Center roboticist Rob Ambrose "The Apollo astronauts couldn't back up at
all because they couldn't see where they were going in reverse." The
vehicle itself has a zero turn radius it can turn around entirely within its
own length (see video).
NASA's Chariot is also the first lunar
drop deck lowboy the Chariot can drop the chassis right down to the
ground for easy loading and unloading.

Science fiction writers have spent a fair amount of time
thinking about how to get around on the Moon's surface. Arthur C. Clarke
thought we might need mass transit:
"The monocab entered a long tunnel at the base of one
of the domes. Sadler had a glimpse of great doors closing behind them then
another set, then another. Then there was the unmistakable sound of air surging
around them, a final door opened ahead ..."

[1955])
Clarke also created a practical vehicle for towing material
around on the Moon's surface that took advantage of the powdery lunar soil -
the dust-ski, which moved like a jet-ski through deep lunar powder:
"At that very moment ... one of the searching dust-skis
was passing directly overhead. Built for speed, efficiency and cheapness ... It
was, in fact, no more than an open sledge with seats for the pilot and one
passenger each wearing a space suit and with a canopy overhead to give
protection from the sun. A simple control panel, motor and twin fans at the
rear, storage racks for tools and equipment that completed the inventory. A
ski going about its normal work usually towed at least one carrier sledge
behind it ... "

Fall of Moondust [1961])
Robert Heinlein thought that lunar prospectors might want to
have something more personal for travel and hauling:
"The solitary prospector, deprived of his traditional
burro, found the bicycle an acceptable and reliable, if somewhat less
congenial, substitute. A miner's bike would have looked odd in the streets of
Stockholm; over-sized wheels, doughnut sand tires, towing yoke and trailer,
battery trickle charger, two-way radio, saddle bags and Geiger-counter mount
made it not the vehicle for a spin in the park but on Mars or on the Moon it
fitted its purpose the way a canoe fits a Canadian stream. "

Rolling Stones [1952])
