It is no secret that the Fourth of July is one of the deadliest days for drivers each year. Outside of New Years' Day, Independence Day commonly has the most alcohol related car crashes in Arizona (and across the United States). Because of this, law enforcement agencies in Phoenix and across the state will be out in force to enforce drunk driving laws.
Drivers can expect additional patrols as well as sobriety checkpoints. Also, police may incorporate "no refusal" tactics to ensure that a person complies with a request to test his or her blood alcohol content (BAC).
Before this happens, police must stop a vehicle (which can be a danger for drivers in and of itself). With that said, below are some tips on how to handle a drunk driving stop.
Be courteous - It may go without saying, but being mean, sarcastic or aggressive towards the officer only heightens their suspicion that you have done something wrong, and can lead to the officer ordering you out of the vehicle.
Avoid sudden moves - To the police, sudden moves are aggressive moves, and they are trained to guard against such moves because they may be the difference between life or death to them (even if you don't intend any harm). Because of this, keep reasonable eye contact with the officer and ask if you can reach for something (such as your registration) before doing so.
Don't try to "talk your way out of it" - Trying to talk your way out of a ticket (or an arrest) is a fool's errand. Whatever you say or do will be used against you even before you are read your Miranda rights.
