As vehicles grow ever larger in the United States, their “safety” benefits for drivers diminish while the danger for pedestrians and other drivers rises. From SUVs to oversized pickup trucks, the shift toward heftier cars has become normal for many drivers seeking a sense of security. But beyond a certain weight, these vehicles offer no extra safety to drivers and make the roads more hazardous for others. Removing just the heaviest vehicle fleet could save many lives on the road.

Reducing lanes for cars doesn’t slow 911 response
Road diets, for example, converting 4 lanes into 3, provide many benefits including traffic calming and improved safety for drivers, bicyclists, and pedestrians. Agencies implementing road diets have seen a 29% average reduction in crashes. However, they often face pushback when planning these conversions, especially from those concerned about potential delays for emergency response. New research suggests these conversions don’t delay emergency response vehicles, meaning they could offer a more balanced approach to safety.
More attentive driving is a small win in tackling traffic deaths
New data shows distracted driving in the U.S. fell by 4.5% in 2023—its first decline since 2020. This offers some hope in addressing the nation’s awful traffic safety record, and it may have contributed to a 3.5% drop in traffic deaths that year. But distracted driving is just a small piece of the puzzle and should not keep transportation professionals from addressing the root causes of our safety crisis.
There isn’t a one-size-fits-all strategy to reduce car usage
Reducing the amount we drive is critical for cutting emissions while also improving health, safety, and transportation system performance. This effort requires both changes in the built environment and individual travel behaviors. The strategies for doing so typically fall into two categories: soft strategies, which focus on incentives and changing attitudes, and hard strategies, which involve infrastructure improvements and new regulations.
Smaller infrastructure investments help pave the way to safer communities
Road safety is an urgent issue at all levels of government, especially for people walking and biking. Cyclist and pedestrian deaths have increased by. This infrastructure week, we are encouraging more states, cities, and other local governments to help reverse this trend by prioritizing critical safety investments on streets and highways across the country.
People on bikes are vulnerable and don’t need to be reminded
Late last month, the Texas DOT posted a message on X (formerly Twitter) urging cyclists to behave better. But this message garnered at least 250 frustrated responses. The echo chamber of X obviously is not a representative sample, but the backlash reflects real challenges that cyclists face every day. Unfortunately, people who bike—along with those who walk, take transit, or face other mobility issues—experience a world where most drivers do not follow the rules, which often puts them at a dangerous disadvantage.
Pedestrian deaths spike right after sunset
As pedestrian deaths continue to rise, it has become clear that most of these deaths happen at night. But a new study finds that the half hour after sunset is the most dangerous in the United States. This worrisome trend is exacerbated by the high-speed, multilane roads that predominate in the U.S. The solutions, in addition to improved visibility, are the same at night as they are during the day: policy, design, and behavior changes that encourage safer, slower driving.
Speed cameras lower speeds and prevent crashes, new research confirms
The Safe System approach to preventing traffic deaths and serious injuries requires us to rethink every aspect of our transportation system, from road and vehicle design to our pervasive car culture. Many communities have found that automated traffic enforcement is one valuable step along the way. As more of these systems are deployed, researchers continue building knowledge about how they work and where they are most effective.
American roads are not ready for massive electric vehicles
Electric vehicles are slowly gaining popularity, and many see them as the key to drastically cutting transportation emissions. Yet the growing weight and size of vehicles are presenting new challenges and serious safety concerns. One major issue is the enormous weight of popular EVs and the impact that these increasingly large vehicles will have on the country’s roads, bridges, and—as one new study points out—its guardrails.
Narrow lanes are safer, but they can be extremely difficult to build
A study released by Johns Hopkins last November gained widespread attention for demonstrating that 9-foot lanes are often safer than wider lanes. The researchers note, however, that most state DOTs set minimum lane widths between 10 and 12 feet and require design exceptions for anything narrower. Even in Vermont, where 9-foot lanes are allowed, the researchers found they have not been implemented. Therefore, paving the way to narrow lanes means understanding all the factors that make them challenging in the first place.
