At times when we’re in a traffic jam, we thought there must be some incident happening up ahead, probably roadblock or traffic jam or a breakdown vehicle. However, when we reach the end, the jam disappears for no reason, and traffic flow resume back smoothly. And we wonder why.

Nobody likes to be in a traffic jam, be it a crawling speed or bumper to bumper. It’s a waste of our time, and also our vehicle’s fuel. But up ahead, a nut-head did something so small yet so sudden, and results in you paying it with your free time. That’s right, the frequent braking that you do might not be a result of some big incident up front, but merely because of someone deciding to change lane all of a sudden.

The next time a traffic jam’s iron grip has you in its clutch, you can at least take heart knowing that scientists have figured out why they happen and who’s to blame. Follow the jump for this latest infographic on the Science of Traffic Jams by Car Insurance Guide. It also sucks to know that you can do nothing about it.
