(CNN) — If you're going to spend 10 months of the year on the road, you'd want a pretty sweet ride.
For truckers in India, that means a kaleidoscope of colors, slogans, and intricately painted symbols that are as much about bling -- as shrewd business sense.
Here, a truck isn't just a way to get around. It's a moving work of art reflecting the character of its driver -- and a brilliant beacon for new customers.
"A better looking truck attracts more business," says Shantanu Suman, graphic designer and filmmaker behind 2013 documentary "Horn Please," which explores India's spectacular truck art tradition.
"Imagine the truck is like a moving billboard. It travels from one side of the country to the other, carrying the message of the truck driver and owner."
Home on wheels
In a nation spanning almost four million square kilometers, truck drivers are the ones quite literally keeping the Indian economy moving -- delivering goods to rural parts of the country inaccessible by railway.
It's a job which entails long months on the road, and these hefty vehicles transformed into mobile homes away from home, kitted out with bunk beds and photos of loved ones far away.
For trucks drivers in India, their vehicle is a home away from home.
"Since they're missing their kids and wives, they like to decorate their trucks with ornaments to remind them of home," explained Suman.
"They might adorn the cabin with bangles -- things that remind them of their wives."
The symbolism continues on the richly painted exterior, with images of gods and goddesses, Bollywood stars, and political logos that say much about the person behind the wheel.
"There's also a lot of decoration that has to do with luck on the road and warning away bad omens. There's a little demon face they put on the front of the truck, or they might tie shoes to the bottom which is meant to keep away the evil eye."
Come face-to-face with the luminous rear end of one of these trucks, and you'll also likely see the words "Horn Please" emblazoned across the back.
It's a call for other drivers to honk their horns when overtaking the truck; a long-standing tradition on Indian roads.
But whether the tradition of truck art itself will continue, is less certain.

"Truck painting is now undergoing a transformation. A lot of things that were once hand painted are now being replaced by stickers," explained Suman.
"Some of these truck artists who have been carrying forward this profession for generations, now don't want their kids to do it because they realize the hardship. They say: 'I want my kids to go to collage and work in an air-conditioned office, rather than be here in the sun painting trucks all day.'"
That said, it's still a skill both artist and driver take huge pride in -- and the journey isn't over yet.
