A genius road design in Iran is making waves online for forcing drivers to follow the rules or risk blowing out their tires.
It’s a low-tech but highly effective system that punishes bad driving instantly, with no cameras, no cops, just cold, hard steel.
In a video filmed on a busy street, what looks like an ordinary metal grate hides a clever mechanism – beneath it are angled spikes that flatten only when a vehicle moves in the correct direction.
Try to go the wrong way, and those same spikes stay upright, ready to puncture your tires on contact.

Why is this genius road design in Iran there?
Sometimes local governments take drastic action to try and get people to follow road rules in their cars.
But in this video, you can see the solution that lawmakers in Iran have gone with when it comes to stopping people from going the wrong way on the road.
Each section of the grate on the road is spring-loaded to respond to the direction of pressure.
When a car or rickshaw drives over it properly, the fins dip slightly to let the tires pass safely.
But, when approached from the opposite side, they lock in place, sharp enough to pierce through rubber and stop any potential rule breaker in their tracks.
These grates are often installed at entry and exit points where wrong-way driving or illegal U-turns are common.
The video shows a bright yellow rickshaw carefully crossing the grate, proving the design works flawlessly for those who respect the rules.
Say sayonara to your tires, rulebreakers!
In cities where traffic can get chaotic, drivers often find creative ways to bend the rules.
This simple deterrent changes that completely because it doesn’t rely on electricity or surveillance, just smart design that enforces discipline automatically.
It’s a perfect example of engineering meeting everyday problems head-on – no fines, no warnings, just a system that makes sure you drive the right way, or pay the price in constant new tire replacements.
