Salt can also help in emergencies. If you ever get stuck on ice, salt sprinkled under the tires can improve traction enough to get moving again. It’s not magic, but it can make the difference between spinning uselessly and pulling free. Keeping salt already in the car means you don’t have to rely on finding sand or gravel when you’re stranded. Some drivers even keep a second sealed bag in the trunk just for winter conditions, especially in rural or icy areas.
There’s no complicated setup. Plain table salt works. Rock salt works even better. The key is leaving it uncovered so it can do its job. Many people use a sturdy glass or plastic container and tuck it into a cup holder or under a seat where it won’t spill. Over time, you’ll notice the salt clumping as it absorbs moisture—that’s proof it’s working. When it becomes damp and heavy, simply replace it with fresh salt.
It’s one of those tricks that sounds too simple to matter until you realize how often visibility and moisture affect driving safety. Clear windows mean quicker reaction time, less distraction, and fewer risky moments on the road. That’s why the officer shared it without hesitation. Not every useful driving tip involves technology or expensive upgrades. Sometimes the smartest solutions fit in a cup and cost almost nothing.
