When you see someone who has been drinking, you usually have to rely on your senses to determine whether they are intoxicated. Slurred speech, uncoordinated movements, and alcohol-laced breath are often the surest hallmarks of intoxication, but these clues require context--and can easily be masked. Thankfully, nothing can fool a breathalyzer.

Whether you're an occasional or habitual drinker, a DUI is a sure sign that you need to exercise more caution during your nights out. Drunk driving is responsible for thousands of car accidents each year, and police are getting more strict about enforcing DUI laws. Some states are even lowering the legal limit, so that a BAC (blood alcohol content) that was once permissible is now considered dangerous.

Anyone who has been pulled over for a DUI will tell you that it's a costly and embarrassing process. What's more, most states will revoke your license if you are caught driving under the influence again. However costly and embarrassing one DUI is, a second one will be much more than an inconvenience--so take steps to make sure you don't drive drunk.

Carrying a personal breathalyzer is the surest way you don't get behind the wheel unless you're sober. These devices are accurate and discreet--so you can carry one in your pocket without anybody noticing. All you have to do is blow into the device. It displays your BAC, eliminating any questions you may have about whether you should drive home or call for a ride.
