Cultural variance makes visiting other countries both exhilarating and challenging. Some differences are intensified when adding a country's driving habits into the mix.

But what exactly do these driving deviations look like for two common functions: honking the horn and flashing headlights? BBC Autos sifted through responses on Quora.com,
the question and answer community, for first-hand perspectives from across the globe.

Honking is not just about displeasure

When it comes to the horn, usage is rampant worldwide even if the reasons for sounding off vary. Quora user Jan Leadbetter wrote,
"Honking the horn in England is a sign of the honker's discontent, or road rage, take your pick."

Americans may be able to relate, but maybe not as much as drivers in India. Tamanna A Shaikh said, "In India, honking is used very liberally. Imagine a noisier,
angrier New York City where everyone is driving like a cab driver." She added that in such conditions, “honking is used mainly to ask the driver ahead to move over or drive faster."

Sabarish Bharadwaj elaborates, noting that honking in India is a big – and sometimes the only – way to communicate with other drivers. "We don't stop or slow down at
intersections, we honk (or just flash the beams at night),” he wrote.
“If there's another vehicle coming to the intersection, they respond with their horn, and then you slow down."
