Promote safer speeds in all roadway environments through a combination of thoughtful, equitable, context-appropriate roadway design, targeted education, outreach campaigns, and enforcement.
The Department believes it is important to prioritize safety and moving individuals at safe speeds.1 Both exceeding the posted speed limit and driving too fast for conditions are speeding-related crash factors.
The Effects of Speed on Roadway Fatalities
Speeding increases both the frequency and severity of crashes, yet it is both persistent and largely accepted as the norm amongst the traveling public.2 Unsafe speeds are a well-documented and understood factor in death and injury, especially among people outside of a vehicle. Managing speeds and addressing issues of speeding will improve safety.
Impact Speed and a Pedestrian’s Risk of Death
Speeding is a significant contributor to deaths on our roadways and is particularly hazardous to pedestrians. Yet, speeding remains worryingly common.

Achieving Safe Speeds
In alignment with the Safe System Approach, achieving safe speeds requires a multifaceted, equitable approach that leverages road design and other infrastructure interventions, speed limit setting, education, and enforcement.
Roadway design and other infrastructure factors play a significant role in managing speeds and can deter excessive speeding behaviors from occurring in the first place.
