Helmets

Motorcycle Riders

All motorcycle riders, regardless of age, must wear a helmet that meets the minimum safety standards as defined by the Department of Transportation (DOT).

The same rules apply to moped and motorized scooter riders.

ATV Riders

The Massachusetts Recreation Vehicle Safety Laws clearly state that all recreational vehicle riders must wear approved helmets.

Bicycle Riders

Bicycle riders who are 16 years old or younger must wear helmets when they are riding on bicycle paths, public ways, and public right-of-ways.

Chapter 85: Section 11B of the General Laws of Massachusetts further outlines other bicycle-related laws.

Headlights

You must use your headlights:

  • A 30 minutes after sunset to 30 minutes before sunrise.
  • When adverse weather conditions make it difficult to see, including rain, snow, and fog.
  • Whenever you must use your windshield wipers.
  • When you can't clearly see other people and vehicles in front of you.

Too, you're allowed to use your headlights to flash other drivers who aren't using theirs when they should be. For more tips on using your headlights in MA, check out Chapter 3: Safety First of the Massachusetts Driver's Manual.

Unattended Motor Vehicles

When you leave your motor vehicle unattended for any period of time, it's safest to:

  • Turn off the engine.
  • Lock the ignition.
  • Set the brakes.
  • Remove the key.

Unattended Children and Pets

Aside from the fact that it may be illegal in your municipality, you risk:

  • Injury and death (especially in hot or cold weather).
  • Kidnapping or petnapping.
  • Curious children or rambunctious pets pushing pedals or turning keys.

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:

Medical Affairs Branch
P.O. Box 55889
Boston, MA 02205

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.
