Typically when an officer stops a vehicle and finds an illegal drug inside, he will request that the person submit to a urinalysis in order to determine if there is any drug in the person’s system. Some drugs, including marijuana can stay in the person’s system for 30 days. If a person smokes marijuana, then he/she is at risk of receiving a DUI if pulled over in the proximate 30 days.
Possession of a drug does not normally affect a driving record. However, the MVD is an independent agency and has a tremendous amount of discretion over the privilege to drive. If, for example, the MVD believed that there was evidence that a drug was in the driver’s system while driving, it could suspend driving privileges. Also, a person can request a copy of their driving record to see what infractions are noted on it.
