Speed is involved in about one of three fatal crashes, according to NHTSA
There are many reasons why people speed. According to Focus on Safety: A practical Guide to Automated Traffic Enforcement, drivers speed because:
They are in hurry
They are inattentive to their driver
They don't view their driving behavior a dangerous.
They don't expect to get caught.
Some or all f the above.
SPEEDING RESULTS IN:
Lives lost - over 10,219 in 2013 - www.nrd.nhtsa.dot.gov
Work zone crashes and fatalities - speed was a factor in 27 percent of fatal crashes in construction and maintenance zones in 2005.
Unsafe school zones - compliance with lower speed limits is poor
Economic cost - speed related crashes cost society over $40 billion annually according to NHTSA. Every minute "gained" by speeding to a destination costs U.S. society over $76,000
SPEEDING
People often think of highways as a major factor for speeding fatalities, perhaps because speeds are highest on highways. But the vast majority of speeding-related fatalities happen on roads that are not interstate highways. NHTSA's 2006 fatality data shows that 47 percent of
speed-related fatalities occurred on road posted at 50mph or less, and more than 20 percent occurred on roads posted at 35mph or less.
