This section is all about keeping yourself, your passengers, and everyone around you safe on the road. It covers the equipment your vehicle needs, how to protect people with seat belts and child seats, and the habits of defensive driving. Crashes are a leading cause of death for young people, so these aren't just rules — they're the choices that keep you alive.
Safety belts are the single most important thing you can do — worn correctly, they cut the chance of death or serious injury in a crash by about half. Massachusetts law requires everyone in the vehicle to be belted or in a child restraint, and young children need an approved car seat until they reach the age or height limit. Air bags work together with belts, not instead of them, so buckle up every time.
Distraction and speed are where many crashes begin. The Hands-Free Law means drivers 18 and older may only use a phone in hands-free mode, and drivers under 18 can't use a mobile device at all except to report an emergency. Leave room ahead using the three-second rule, use your headlights whenever your wipers are on, and slow down for rain, snow, and ice.
Does everyone in the car really have to wear a seat belt?⌄
Yes. Massachusetts law requires every person in a passenger vehicle to wear a safety belt or use a proper child restraint. The driver can be fined for unbelted passengers who are 12 to 15, and it's the smartest habit you can build.
Can I use my phone while driving?⌄
If you're 18 or older, you may use it only in hands-free mode — mounted, not held in your hand — and not while stopped at a red light. Drivers under 18 may not use any mobile device at all, except to report a real emergency.
How much space should I keep behind the car ahead?⌄
Use the three-second rule: pick a fixed point, and you should pass it at least three seconds after the vehicle in front. Give more room in bad weather, behind a motorcycle (four seconds), or behind heavy trucks that need extra stopping distance.
