Motorcycle cop making a stop

Before you can be charged with an OUI in Maine, a police officer must stop your vehicle. Police must have a reason for stopping drivers. Observing a driver leave a bar on a weekend is not a valid reason. If you are arrested for DUI and your Maine OUI defense lawyer can prove that your stop was unlawful, your charges may be dropped.

In the state of Maine, an officer must have reasonable articulable suspicion before they have the legal right to stop your vehicle. This means that an officer must have reasonable, lawful grounds for stopping a motorist. An officer can pull you over for any traffic or safety violation, and if you are driving under the influence (DUI) at the time of your stop, you could be arrested and charged with drunk driving.

What are the protocols of an OUI Stop in Maine?

The first step in every arrest is the evaluation process. A police officer will ask you to undergo sobriety testing if they feel that you are showing signs of intoxication. To get to this point, however, you need to be stopped by police. There are 3 main ways that can lead a driver to being arrested for OUI, they include:

Traffic Stops

Many DUI charges result from simple traffic violations, such as speeding, drifting within the lane or across traffic or fog lines, swerving, driving erratically, or driving at night without using your headlights. Whether you were stopped because the officer suspected you were under the influence or for a routine traffic offense, you will face serious consequences if charged and convicted of a DUI, also known as DWI or OUI. If you were stopped without good reason, however, you may be able to fight the charges brought against you due to the violation of your rights.

The officer must have a good reason for stopping you in order for the evidence of drunk driving to be lawful. For instance, if you were stopped at 3 a.m. because you were driving well under the speed limit and swerving across lanes, the officer would have a reasonable articulable suspicion. On the other hand, if the driver pulled you over simply because you were on the road at 3 a.m., despite the fact that you were following all traffic laws, they would not have legal grounds to stop you and a good DUI defense lawyer can get the case thrown out.

Random Checkpoints

DUI stops can also be made at random checkpoints. Checkpoints are legal under the federal Constitution. Police set up a roadblock and randomly check the BAC of drivers as they pass through.  Checkpoints are a legal way to stop drivers, but only if certain protocol are followed. Police officers cannot simply decide to start stopping vehicles in a certain area and they must prove that those stopped were at random. Checkpoints must stop all vehicles that come through and must keep the stops brief. If you were stopped at an illegal checkpoint, your case may be dismissible. For more information about how to find out if the checkpoint where your DUI arrest took place was legal, contact an attorney.

If a car is observed by police approaching a checkpoint and then turning around or maneuvering in some way that implies the driver may be intentionally avoiding going through the checkpoint, the law says that this is probable cause for police to stop that vehicle. The idea is that the driver has something to hide and is attempting to avoid arrest. There are, however, many other reasons that a driver could be turning around.

Scene of an Accident

When police respond to the scene of a traffic accident where serious injury or death have occurred, they will often evaluate all drivers for signs of intoxication. In fact, in cases of serious bodily injury or death, the driver will be forced to submit to a blood draw in order to determine if he or she was under the influence of alcohol.  Even if you are the victim of an accident, you could still face OUI charges if you are found to have been impaired by drugs or alcohol at the time of a car accident.
