Search Speed Limits

The NMA's Position

Speed limits should be based on sound traffic-engineering principles that consider responsible motorists' actual travel speeds. Typically, this should result in speed limits set at the 85th percentile speed of free-flowing traffic (the speed under which 85 percent of traffic is traveling). These limits should be periodically adjusted to reflect changes in actual traffic speeds.
