Too many people are pulled over for the silliest reasons, very few of which can be attributed to drunk driving. For example, if you are reaching for your cell phone or fiddling with the radio, you may have caused your vehicle to veer to one side. This does not mean that you are drunk. It certainly does not mean that your driving was affected by your drinking. If the officer is going to claim that your driving showed signs of your intoxication, an alternate explanation for your driving will come in very handy in demonstrating that the officer's presumptions about your driving are wrong. A good Michigan OWI lawyer knows it's important to aggressively defend the basis for stopping you, since an illegal stop of your vehicle often times means a dismissal of your case. After all, no evidence obtained against you on the basis of an illegal stop can be used against you in court. Your attorney must look for any and all reasons to challenge the reason the officer stopped you, since doing so will reveal many legal opportunities for your DUI defense in court.
