In general, the right to remain silent means that it is up to the individual whether to answer the police questions. However, in some cases, the person has to identify him/herself and to provide an address. For example, a driver has to identify him/herself and to produce his/her driver’s licence when stopped by the police. In some other cases, there may be a statutory obligation to provide the police with information (e.g., the registered owner of motor vehicle involved in an accident). It is best to consult a criminal lawyer if you are not sure whether you are obliged to answer police questions.
