You might think that puffing on a cigarette while driving down the road is no big deal, but the truth is, it comes with some serious drawbacks. For starters, it’s a major distraction – your attention gets pulled away from the road, which always increases the chances of a collision. And that’s not all – besides reducing your reaction time, smoking can also hamper your visibility when the smoke obscures what’s happening around you.

But wait, there’s more. If you’ve got company in the car, like friends or family, they’re basically along for the secondhand smoke ride as they end up breathing in harmful carcinogens with you. And, if you’re in California, there’s a law you should know about that says you can’t light up in a car, whether it’s moving or parked, if there’s anyone under 18 present.

So, the next time you’re tempted to smoke behind the wheel, you might want to think twice – for your safety and everyone else’s too.
