Tips for Driving Safely Near Big Trucks in Massachusetts

The Short Answer:

Driving safely near big trucks involves staying out of their blind spots, leaving extra following distance, and passing promptly on the left. Avoid driving directly beside or behind a truck for an extended period. Never cut closely in front of one or move between a turning truck and the curb. Because large trucks are heavier and less maneuverable than passenger vehicles, they need more room to stop, turn, merge, and change lanes. Use your signals early, avoid sudden movements, and increase your distance in poor weather or heavy traffic.

Why Do Drivers Need To Use Extra Caution Around Large Trucks?

Large trucks operate differently from passenger vehicles because of their size, height, and weight. They accelerate more slowly, need more room to stop, and can’t change direction as quickly. Drivers should avoid sudden braking or lane changes near a truck because its driver may not have enough time or space to respond.

Trucks also have large blind spots in front, behind, and along both sides. Their length requires them to swing wide when turning, particularly when making a right turn. Motorists should remain visible, leave extra space, and avoid traveling directly beside a truck for longer than necessary.

Wind gusts from a passing truck can make a smaller vehicle harder to control. Trucks may also create heavy road spray during rain or throw snow and slush into nearby lanes. Keeping a safe distance gives motorists more time to see changing conditions and react safely.

10 Tips for Driving Safely Near Large Trucks

Large commercial trucks have bigger blind spots, need more room to stop, and can’t move as quickly as passenger vehicles. The following tips can help you account for those differences when sharing Massachusetts roads with tractor-trailers and other commercial trucks:

#1. Stay Out of a Truck’s Blind Spots

Large trucks have 4 main blind spots, sometimes called “No-Zones.” These areas are directly in front of the cab, directly behind the trailer, along the driver’s side, and along the passenger side. The blind spot on the passenger side is especially large and may extend across several lanes.

Use the truck’s side mirrors to determine whether the driver can see you. If you can’t see the driver’s face in a side mirror, assume the driver can’t see your vehicle. Don’t remain beside a truck longer than needed. Move ahead at a safe speed or slow down and fall behind it.

Be especially careful near ramps and lane changes. A truck driver may begin moving into your lane without realizing that your vehicle is beside the trailer. You can learn more about where these areas are in our guide to tractor-trailer blind spots.

#2. Leave Additional Following Distance

Following too closely behind a truck can place your vehicle in its rear blind spot. The truck driver may not know you’re there. A trailer can also block your view of traffic lights, brake lights, road debris, work zones, and stopped vehicles ahead.

Leaving more space gives you a better view of the road and more time to respond. It can also prevent an underride collision in which a smaller vehicle slides beneath the back of a trailer.

Additionally, don’t stop too close behind a truck on a hill. A heavy truck may roll backward slightly when it begins moving. Leave enough room to change lanes or move out of the way if necessary. Increase your following distance further during rain, snow, ice, heavy traffic, or other conditions that make stopping more difficult.

#3. Pass Large Trucks on the Left

Pass a large truck on the left whenever it is safe and legal to do so. The driver has better visibility on the left side of the cab than on the passenger side. Before passing, check that you can see the driver in the truck’s mirror, signal your lane change, and make sure the lane ahead is clear.

Pass at a safe, steady speed without exceeding the posted speed limit. Avoid remaining beside the truck, especially near the trailer’s rear wheels. Once you’ve passed them, wait until you can see the entire truck in your rearview mirror before returning to its lane. This helps ensure that you’ve left enough room in front of the truck.

Avoid passing a truck on the right whenever possible. You should also avoid passing while traveling downhill because a heavy truck may gain speed. If road or traffic conditions don’t allow you to complete the pass safely, remain behind the truck until a better opportunity becomes available.

#4. Don’t Cut Closely in Front of a Truck

Large trucks need much more space to slow down or stop than passenger vehicles. If you merge too closely in front of one, the truck driver may not have enough time or distance to avoid hitting your vehicle.

A truck also has a blind spot directly in front of its cab. The driver may lose sight of a smaller vehicle that moves into this area. Using a turn signal doesn’t mean there is enough room to merge. Your signal shows what you plan to do, but you must still wait for a safe gap.

Before returning to the truck’s lane, make sure the entire truck is visible in your rearview mirror. Maintain your speed after merging and avoid braking suddenly.

#5. Give Trucks Room To Make Wide Turns

Large trucks require additional space to complete turns. A truck making a right turn may first move toward the left side of its lane or into a nearby lane. This movement doesn’t mean that the driver is turning left or inviting other vehicles to pass on the right.

Never move between a turning truck and the curb. The truck’s cab and trailer follow different paths through a turn, and the trailer may move across the space beside it. Wait behind the truck until it finishes turning.

Stop behind marked lines at intersections so trucks have enough room to cross or turn. Don’t block an intersection, even when traffic ahead begins moving. Waiting a few extra seconds can prevent you from becoming trapped in the truck’s path.

#6. Use Signals Early and Avoid Sudden Maneuvers

Use your turn signal well before passing, merging, or changing lanes near a truck. An early signal gives the truck driver more time to notice your vehicle and respond to your movement.

Avoid abrupt lane changes beside a truck. You could enter a blind spot before the driver knows you’re there. Sudden braking in front of a truck is also dangerous because the truck may not be able to slow down as quickly as your vehicle.

Don’t depend on eye contact or assume the truck driver is allowing you to merge. Make sure there’s a clear opening before moving. Predictable movements make it easier for everyone around you to respond safely.

#7. Be Patient Around Slow-Moving Trucks

Wait for a safe and legal opportunity to pass. Make sure you have enough time to pass the entire truck without speeding or cutting in front of it. If you can’t see far enough ahead to complete the maneuver, remain behind the truck.

Again, trucks can gain speed while traveling downhill. A truck that was moving slowly uphill may approach more quickly on the other side. Avoid pulling in front of it without leaving plenty of room.

#8. Know What To Do When a Truck Passes You

When a truck begins passing your vehicle, maintain a steady speed or slow down slightly if it’s safe. Don’t accelerate or make it harder for the truck to complete the pass. Just keep to the right side of your lane without driving onto the shoulder.

You may feel a change in air pressure as the truck approaches and moves past you. Keep both hands on the wheel, look ahead, and hold a steady position within your lane.

After the trailer clears your vehicle, leave enough space for the truck to merge back into the lane. Avoid moving into the truck’s lane or blind spot while it’s completing the pass.

#9. Prepare for Wind, Rain, Snow, and Road Spray

Bad weather can make driving near large trucks more difficult. A passing truck may create a strong wind gust, particularly on an open highway or bridge. Keep both hands on the wheel and be prepared to correct your position without making a sudden movement.

Truck tires can create heavy road spray during rain, reducing your ability to see the road and nearby traffic. Increase your distance instead of driving directly beside the truck. Use your headlights and windshield wipers as needed, and reduce your speed based on road conditions.

Use the same caution during snow or icy weather. Don’t remain beside a truck on a slippery road, and watch for snow or ice that could fall from the cab or trailer. Increasing your distance gives you more time to respond without sudden braking or steering.

#10. Use Extra Caution in Traffic, Work Zones, and Merging Areas

Highway ramps, lane closures, and work zones can force trucks into smaller or changing spaces. Watch for turn signals and give trucks room to enter traffic or change lanes. Avoid remaining beside a truck when lanes narrow, shift, or end.

Expect trucks to move and stop more slowly in work zones. Leave extra following distance and watch for signs, flaggers, construction vehicles, and changing traffic patterns. Don’t enter a gap that a truck needs to merge.

These precautions are also helpful in heavy Boston-area traffic and on crowded Massachusetts highways. When traffic slows, avoid stopping in a truck’s blind spot or blocking its path at an intersection. A little patience and extra space can make your movements easier for the truck driver to see and predict.

What Should You Do If a Truck Begins Moving Into Your Lane?

If a truck begins moving into your lane, stay calm and avoid making a sudden turn that could send your vehicle into another lane or off the road. Then take these steps:

1. Maintain control of your vehicle and look for a safe path away from the truck.
2. Don’t accelerate alongside the truck or attempt to pass it.
3. Use your horn briefly to alert the truck driver to your presence.
4. Slow down when it’s safe and move out of the truck’s blind spot.
5. Check your mirrors and blind spots before changing lanes.
6. Move into an adjacent lane only if it’s completely clear.

Keep watching the traffic around you throughout the situation. Other drivers may also brake or change lanes in response to the truck. If no lane is open, reduce your speed carefully and create as much distance as possible without losing control of your vehicle.

General Safe-Driving Habits Matter Around Trucks

Basic safe-driving habits are especially helpful when sharing the road with large trucks. Follow the posted speed limit and reduce your speed when traffic, weather, visibility, or road conditions make the limit unsafe. Driving at a reasonable speed gives you more time to recognize a truck’s movements and respond without sudden braking or steering.

Wear a seat belt every time you drive, and make sure every passenger is properly restrained. Put your phone away and avoid adjusting navigation, eating, or doing anything else that takes your eyes or attention off the road.

Never drive while impaired by alcohol, drugs, fatigue, or medication that affects your ability to stay alert. Keep watching all the traffic around you instead of focusing only on the truck. Changes in nearby lanes, slowing vehicles, and approaching ramps may affect how both you and the truck driver need to respond.

Safe driving can reduce the risk of a collision, but motorists can’t control the actions of truck drivers, trucking companies, or other road users. When a truck accident occurs, determining what caused it may require reviewing driver conduct, vehicle maintenance, loading practices, and company records.
