Speeding isn’t just exceeding the posted speed limit. Driving too fast for current weather and road conditions also is considered
speeding.

In the best of conditions, the average time it takes for most drivers to process what is happening
ahead of them and to begin to apply the brakes is 1.5 seconds.*

The faster your vehicle is going, the farther
the distance traveled while you process what is happening ahead of you.
Speed Affects Distance Traveled During Reaction Time
4 / 15Slide5
Processing what is happening ahead of you and getting your foot on the brake are both components of
human factors, meaning they can be affected by:
Drowsiness and/or fatigueAlcohol consumptionUse of some over-the-counter or prescription drugs
Manual, visual or cognitive distraction

The faster you drive, the greater the severity of impact and
the energy that must be absorbed.

Drivers are twice as likely to kill a pedestrian on impact if they are traveling at 30 mph (50 km/h) vs. 25 mph (40 km/h

The effectiveness of restraint devices like air bags, seat belts, crumple zones and side beams decline as impact speed increases.

Speeding Saves Very Little Time
On a 5-mile trip, driving 65 mph (104 km/h) on a
45-mph (72 km/h) road saves less than 2 minutes.*

Ways to Avoid Speeding
Careful route planning saves more time than speeding. Check traffic apps before you leave to
help avoid congestion.
Full mirror sweeps are recommended every 5-7 seconds. Include checking the speedometer to keep your eye on your speed and avoid accidental
speeding.
Use cruise control selectively. Set at a legal, safe speed, taking into account
weather and road conditions. Cruise control is not recommended on city
streets, in heavy traffic, on hilly,
curvy,
slippery, wet, snowy, or icy roads.
Consider a driving playlist or tune in to an “easy listening” station to help reduce stress and help you slow down.
Leave 5-10 minutes
early!

In a motor vehicle crash, an unbelted
occupant actually suffers 3 crashes
*:1) Vehicle collision The vehicle crashes into another vehicle or fixed object such as a guard rail or tree;
2)
Human collision
The body crashes into other occupants
and/or
the interior of the vehicle, or is
thrown
out of the vehicle through one of the windows;
and3)
Internal collision Internal organs crash against each other and/or the body's skeletal structure. Buckle Up
- on every trip, every time. And be sure your passengers do, too.
