Distraction and Parking Lots
LENGTH 2–5 minutes
TO PREPARE Read the background information.
BACKGROUND According to the National Safety Council, as many as 66% of drivers
may be pulling into and exiting out of parking spaces while
distracted.
1 in every 5 crashes occurs in a parking lot or parking garage.
NSC found that at least 60,000 people are injured and approximately
500 people die every year in more than 50,000 parking lot crashes.
Smartphones may be the reason for this alarming trend.
• Texting or talking on the phone is a leading reason for distracted
driving in general.
• The ease one feels in a parking lot may be the reason more
drivers are willing to operate their vehicles while distracted.
• Researchers say slower speeds in parking lots give people a false
sense of security. Even though drivers tend to maintain slower
speeds in parking lots and garages, the consequences of driving
distracted can be devastating.
DISCUSSION Distraction and parking lots can be a deadly combination.
An NSC poll found that as many as two-thirds of drivers may be
pulling into shopping centers distracted.
1 in 5 crashes occur in parking lots.
Pedestrians and children unintentionally left in vehicles are at risk.
What do you think is a leading culprit for distraction?
Smartphones cause the most distraction for drivers, whether they are
talking, texting, checking social media or browsing on a website. The
risk of distraction is deadly.SAFETY HUDDLE
Common Parking Lot Scenarios
A man or woman exiting a vehicle becomes a pedestrian.
• Workers may feel safe walking to the workplace from the parking
lot. However, there may be many other vehicles moving about the
parking lot. Distraction—such as walking to the building while
checking text messages—can cause a worker to miss seeing
these other vehicles.
A driver whose routine has changed may be thinking of the next thing
in his/her day and may inadvertently leave a young child in a vehicle.
Distracted pedestrians also may miss seeing children unattended in
another vehicle in the lot.
• 22% of child heatstroke deaths in vehicles occur at a place of
work.
How quickly can a vehicle interior heat up, even on a cloudy day?
On average, the temperature inside a vehicle increases 19 degrees in
10 minutes.
SUMMARY Even though people tend to drive a lot slower in a parking lot, the
consequences of distraction can be deadly.
People have their heads down; they are on their phones whether they
are behind the wheel or walking through the lot.
