For more information about laws concerning unattended children and pets in your area, contact your local State Police Troop. You may also want to brush up on the laws regarding traveling with animals.
Reporting Unsafe and/or Drunk Drivers
To report a driver whose medical condition or disability makes his or her driving ability potentially dangerous, you file a report with the RMV using a Request for Medical Evaluation. You can mail this form to the address on the form.
However, because the report asks for personal information (Social Security number, driver's license number, and current address), you may not be able to use it to report an unsafe driver whom you don't know well. In this case, it's best to contact the RMV or your local State Police Troop.
For more information, visit the RMV's Reporting Requirements and For Families and Caregivers.
To report a drunk driver, call 911.
