Vehicle searches can be lawfully carried out in Chicago with or without your consent. The penal code in Chicago gives the police many powers so that they can stop criminals and prevent crime. The law specifies the situations in which the police can search a car. Normally these situations arise if there is a strong suspicion that the vehicle contains an illicit substance or a criminal. The search might also be done if there is suspicion that the car has been used or is about to be used to commit a crime. Failure to follow procedures can be grounds for a criminal defense.
Failure to stop and submit to a lawful vehicle search can be a crime. If there is a court case, the fact that the defendant refused the search can be used by the judge and jury to assume that they must have been doing something wrong. This is what is known as an “adverse inference” and can turn a case against the defendant. The evidence that has been found during a vehicle search can be used in a court case such as for drug charges.
