After having some good time in a bar, you would not even dream of getting arrested by an officer under Texas DWI laws. However, having a couple of beers at a bar would certainly intercept your way home. You should note that driving while drinking is not prohibited in many states, but driving while intoxicated is prohibited everywhere.

It is also worth noting here that the law only provides that the crime of DWI occurs when a person drives, and at that time he is intoxicated by having an alcohol concentration of 0.08 or more in his body. Moreover, we should also bear in our mind that it is not a per se crime to have an alcohol concentration of 0.08 in the body either before or after one has driven, but at the time of driving.
