Katy Waldman looked at the relationship between speed limits and traffic fatalities. Highlights include:

• Raising speed limits does not lead to an increase in traffic accidents.
• This is likely because each driver has a ‘comfort speed zone’ that they drive at, regardless of what the posted limit is.
• In fact, raising speed limits can lower the rate of accidents because drivers are much more cautious with higher posted limits around.
• However while the number of accidents stays the same or declines, the number of fatalities increase because each accident is more likely to result in death at higher speeds.
