List one reason why a driver's license may be suspended in Massachusetts.

A driver's license may be suspended in Massachusetts due to accumulating too many points on the driver's record. The state employs a point system to track traffic violations and unsafe driving behaviors. When a driver reaches a certain threshold of points, it indicates a pattern of unsafe driving, leading to increased risks on the road. To ensure public safety, the Registry of Motor Vehicles (RMV) can suspend the license of drivers who demonstrate chronic violations that accumulate excessive points in a specified time frame. This suspension serves as a corrective measure to encourage safer driving practices and reduce the likelihood of accidents.

Other options, such as failure to renew vehicle registration, while potentially leading to issues with the vehicle's legality, do not directly result in the suspension of the driver’s license. Similarly, although an accident caused by poor road conditions can be a factor in unsafe driving, it does not inherently lead to a suspension of the license unless it is connected to other violations or points on the record. Involuntary manslaughter is a serious criminal offense that would lead to far more severe legal consequences than a simple license suspension, as it can include imprisonment.
