The main purpose of a roadside sobriety check is to ensure that drivers are not under the influence of drugs or alcohol. These checks are an essential part of road safety measures aimed at reducing the incidence of impaired driving, which poses significant risks to both the driver and others on the road. During such checks, law enforcement officers typically assess the sobriety of drivers through various means, which may include field sobriety tests or breathalyzer tests.

The focus on detecting impaired driving is crucial because driving under the influence can lead to serious accidents, injuries, and fatalities. These checks are deployed strategically, especially during times or in areas where impaired driving is more likely to occur, helping to deter drivers from taking the risk of driving while intoxicated.

Other options are related to vehicle compliance or safety checks but do not reflect the primary intention of roadside sobriety checks, which is specifically aimed at monitoring drivers' sobriety rather than vehicle conditions or registration status.
