The results of a survey will help state safety officials identify what are the most common distractions that can often lead to accidents.
PennDOT's Jennifer Kuntch said the anonymous survey takes a few minutes to complete.
Kuntch said while most of us might think using a handheld cell phone is the worst kind of distraction – we would be wrong based on the results of last year's survey.
"38% of those surveyed indicated that they were distracted by adjusting the radio or climate controls," Kuntch explained. "And, 37% indicated they were distracted by an object outside the vehicle."
She said cellphone use while driving was below 15%.
"Distractions are everywhere," Kuntch said. "It's not just your cell phone. Driving is a skill that requires 100% of your attention, 100% of your time."
Kuntch asks the public to take the survey during the coming week.
"The results from the survey will help us better understand participants attitudes on highway safety and essentially allow us to adjust safety activities as we work to reduce crashes and fatalities on our roadways," she said.
Kuntch said people's answers will also help PennDOT craft its safety messages spread across a wide range of media.
"Social media, PSAs, dynamic message boards along our highways," she said. "We also have enforcement efforts in areas such as the topics we're surveying – seatbelts, impaired driving, speeding, distracted driving.
"So our enforcement efforts are completed in partnership with state and local law enforcement and that includes things like checkpoints, roving patrols, etc."
