New Berlin, WI (September 11, 2026) – Two people were injured in a five-vehicle crash on Thursday, September 10, on southbound I-43 near Moorland Road in New Berlin.
According to the Waukesha County Sheriff’s Department, the crash happened around 6:25 a.m. A vehicle reportedly failed to stop for slowed traffic, triggering a chain-reaction crash involving five vehicles.
Two occupants were transported to a hospital with non-life-threatening injuries. All lanes of southbound I-43 later reopened, and traffic returned to normal.
Our thoughts are with the two injured individuals and their loved ones. We wish both of them a full and speedy recovery.
How Can Chain-Reaction Crashes Develop on Busy Highways?
Chain-reaction crashes can happen when traffic slows suddenly, and drivers do not have enough time or space to stop. Following too closely can make it difficult to respond when the vehicle ahead brakes unexpectedly. Leaving additional space between vehicles gives motorists more time to slow down and can reduce the force of a rear-end impact.
Looking beyond the vehicle directly ahead can also help drivers recognize developing traffic backups sooner. Brake lights, slowing vehicles, and congestion farther ahead can provide early warnings that traffic is changing. Drivers should adjust their speed before reaching the slowdown rather than waiting until the last moment to brake.
Distractions can make these situations even more dangerous because a driver may not notice that traffic has stopped or slowed. Cellphone use, adjusting navigation systems, and other activities can take attention away from the roadway. Staying focused, maintaining a controlled speed, and allowing adequate following distance are important ways to reduce the risk of a chain-reaction crash.
