What percentage of fatal crashes occur on roads where traffic control devices are in effect?

• A. 5%
• B. 11%
• C. 15%
• D. 22%

Answer: (B)

Traffic control devices guide drivers and reduce risk, but they don’t eliminate it. Eleven percent of fatal crashes happening on roads where these devices are in effect shows that crashes can still be deadly even when signals or signs are present. This often involves situations like running a red light, misjudging yellow lights, failing to yield the right of way, or speeding through intersections. The takeaway is to stay alert and prepared at controlled intersections: slow down as you approach, obey signals, look for other vehicles and pedestrians, and maintain a safe following distance. Distractions and risky driving around these areas can still lead to severe outcomes, so never assume the device will prevent a crash.
