A driver may speed because they are late or simply keeping up with traffic. Yet even a small increase in speed can make a crash much more serious. In Illinois, speed played a major role in all crashes and fatal crashes. These numbers show a few extra miles per hour can have serious consequences on the road.
Why does speed increase crash risks?
Speeding makes it harder for a driver to avoid a crash. At higher speeds, a vehicle needs more distance to slow down or stop. This can become especially dangerous near traffic lights, pedestrians or stopped vehicles. Rain, snow or poor visibility can increase the risk even more.
Illinois law recognizes these dangers. Under the state’s general speed restrictions, drivers must use a reasonable speed based on road and traffic conditions. This means the posted speed limit may not always be a safe speed. For example, a driver may need to slow down during heavy rain or when approaching a busy intersection.
Why does speed make injuries worse?
Higher speeds also increase the force of a collision. Therefore, crashes at high speeds can cause severe injuries even when safety features work as designed.
A person may suffer broken bones, head injuries or damage to internal organs. Pedestrians, bicyclists and motorcyclists face an even greater risk because they have little protection from the impact.
Illinois crash data highlight the danger. In 2024, speed played a role in more than 29% of fatal crashes across the state. Speed-related crashes also increased compared with the previous year.
Why does speed matter after a crash?
After a serious collision, evidence of speeding may help explain how the crash happened. Police reports, witness accounts, video footage and vehicle data may help show how fast a driver was traveling.
However, sorting through this evidence can become difficult while an injured person is recovering. A personal injury attorney can review the facts and explain how Illinois law may apply. Legal guidance may also help an injured person understand the options for seeking compensation after a speed-related crash.
