Distractions behind the wheel go beyond cell phone use and drowsiness, and the proof is in a new survey from CarInsurance.com.

Unless you're guilty as well, you'd be amazed by what some drivers are burdened by, or surviving without, while on the road.

Nearly a third of motorists admitted to driving without being able to see through the windshield due to ice or snow. More than a quarter hit the road with wipers that wouldn't work. Having an arm in a cast didn't stop 8 percent of drivers from getting behind the wheel. An even greater percentage operated a vehicle without wearing their prescription glasses or contact lenses.

Tracy Noble, a spokesperson for AAA Mid-Atlantic, said many drivers have a sense of invincibility on the road, fully believing that they can multitask while driving.

"The fact of the matter is that driving requires a lot of concentration, a lot of thought and a lot of effort," Noble said. "People need to pay attention."

She said when drivers fail to make the road their number one priority, it puts their own lives and other motorists' lives in danger.

"A lot of folks do things that they would absolutely be appalled by if they saw other drivers doing them," Noble added.

The top distraction in the survey was sleepiness. Nearly 70 percent of respondents admitted to drowsy driving. In New Jersey, motorists can be charged with reckless driving if they've been without sleep for 24 hours.
