1 TL Test Before Driving? Experts Issue Critical Warning to Drivers!
Automotive 27 November 2025

Heading out on the road this winter? Before you even think about firing up the engine, experts are urging drivers to perform a dirt-cheap, potentially life-saving tire check using something you almost certainly have in your pocket: a one-lira coin.

The method is ridiculously simple. You just insert a one-lira coin into the main tread groove of your tires. If the outer ring of the coin is visible above the tread, it means your tire tread depth has dipped below the legal minimum of 1.6mm. Translation: your tires are bald, unsafe, and, frankly, illegal.

If the outer ring disappears into the tread, then congratulations, your tires are still good to go (for now, anyway). But don't just do it once! For a more accurate picture, experts recommend checking at least three different points on each tire. After all, tires can wear unevenly, and you want to get a complete understanding of their condition.

Why all the fuss about tread depth? Well, think about it: your tires are the only things keeping you connected to the road. Adequate tread depth is absolutely critical for safe braking, maintaining a solid grip, and channeling water away from the tire surface. Worn tires dramatically increase the risk of hydroplaning – that terrifying moment when your car essentially surfs on a film of water. Trust me, you don't want to experience that, especially on an icy winter road.

Beyond the one-lira test, preparing for winter driving goes beyond just tires. Experts are also stressing the importance of using winter-grade windshield washer fluid. Regular stuff can freeze, leaving you with a useless streak across your windshield just when you need visibility the most. Speaking from personal experience, that's happened to me more than once, and it's never fun.

And don't forget the emergency kit! Keep a blanket, some snacks (because being stranded and hungry is the worst), a flashlight, and a phone charger in your car. A little preparation can make a huge difference if you find yourself stuck in a winter weather situation.

Ultimately, the advice is simple: be extra cautious this winter. "If you feel unsafe or the roads are treacherous, reconsider your journey," experts caution. Sometimes, the best decision is to stay put and wait for conditions to improve. Your safety is worth more than any appointment or errand.
