Driving near trucks, buses and other commercial vehicles can feel stressful. These vehicles are much larger than passenger cars and generally need wider turning areas and more time to respond. Understanding how they move may help you make better decisions each time you drive on Massachusetts roads.
Stay out of blind spots
Trucks and other commercial vehicles have blind spots around the front, sides and rear. Many trucks have larger blind spots along the right side and directly behind them. If you cannot see the driver in the truck’s side mirror, the driver may not be able to see you.
Avoid staying beside a truck longer than necessary. When you pass, keep a steady speed and move back into your lane only after you can see the entire front of the truck in your rearview mirror. Driving where the driver can see you may help prevent crashes during a lane change or turn.
If an accident occurs while you are driving unsafely or lingering in a large vehicle’s blind spot, this behavior may be used as evidence of comparative negligence. Under Massachusetts law, this can reduce your financial recovery or bar it completely if you are found to be more than 50% at fault.
Maintain a safe following distance
Large trucks need much more stopping distance than smaller vehicles, especially when they carry heavy loads. Following too closely or pulling in front of a truck without enough room may create a dangerous situation.
You should maintain several seconds of following distance behind a truck. This added distance gives you a better view of the road and more time to react if traffic changes. If a truck is behind you, avoid sudden braking when possible because the driver may need more time to stop.
Be patient during turns and lane changes
Commercial vehicles often need extra room to complete a turn. A truck may need to move wider before making a right turn to clear the corner. Even if there appears to be enough space, avoid passing between the truck and the curb while the truck is turning.
You can also help keep traffic moving by allowing trucks enough space to change lanes. If you see a truck use its turn signal before merging, consider adjusting your speed when conditions allow. A little patience may help prevent dangerous situations on the road.
Adjust for changing road conditions
Rain, snow, heavy traffic and construction zones can make driving more difficult for everyone. Large vehicles may need even more space to maneuver in these conditions.
You can lower your chances of a crash by staying focused, avoiding distractions and leaving extra room around trucks and other commercial vehicles. Small changes in the way you drive may reduce risk and help create a safer road for you and everyone around you.
Protecting yourself and others on the road
Every trip is an opportunity to practice safer driving habits around large vehicles. By staying alert, leaving enough space and giving trucks room to maneuver, you can help reduce the risk of dangerous situations. Keeping these habits in mind each time you drive may protect you, your passengers and other drivers.
