Don't drive after having anything to drink
Unfortunately, it has been our experience that driving and the smell of alcohol on your breath is usually enough to get you arrested. As the saying goes, "you may be the rap, but you can't beat the ride." If you have anything at all to drink, the best thing to do is avoid driving altogether. In Texas you can be charged with a DWI if your blood alcohol content (BAC) is .08% or higher. I've included a link to a BAC calculator below if you're curious how many drinks would put you over the limit. A word of caution; the BAC calculator only estimates your likely BAC based on your gender, height, weight, and speed of consumption. It should only be used as a reference because actual BAC levels can vary between individuals with the same characteristics dramatically. If you've had any alcoholic beverages to drink, your best bet is to take a taxi or call friend for a ride. Even the smell of alcohol on your breath can lead to an arrest in some cases. Err on the side of caution.
Don't drive after consuming certain prescription drugs
More and more often, we are seeing drivers arrested for DWI because of prescription drugs. Therefore, if you have taken any prescription drugs that can effect your ability to drive or operate a motor vehicle safely, do not drive. Several prescription drugs, while legally prescribed to you, may contain ingredients that affect your ability to drive or operate machinery. Make sure you read these precautions and arrange transportation alternatives appropriately.
