Did You Know...?
- The speed limit on all residential streets in the Unincorporated County is 25 mph unless otherwise posted.
- At 20 mph it takes 46 feet to come to a stop.
- At 30 mph the stopping distance nearly doubles to 87 feet.
- At 40 mph the stopping distance more than triples to 140 feet.
- The effectiveness of restraint devices like air bags and safety belts, and vehicular construction features such as crumple zones and side member beams decline as impact speed increases. (USDOT, NHTSA)
- If you were to crash into a barrier at 45 mph your impact speed would be roughly the same as that reached after falling from a seven story building.
- The travel time savings from an increase in speed is minimal. For example, if you drive 45 mph instead of 35 mph on a five-mile trip, you will save less than two minutes before arriving at your destination. (USDOT, NHTSA)
- Speed, as defined as exceeding the posted speed limit or traveling too fast for conditions, is cited as a contributing factor in approximately 30 percent of fatal crashes. (NHTSA)
