CARSON CITY, NV - 70% of the undocumented immigrants trying to get a drivers authorization card have flunked the written test.
The numbers seem high, but across the state the average failure rate for anyone taking the test is 56%.
Just because a driver is licensed doesn't mean he or she knows all the rules of the road.
"I would venture to guess that if you took a group of average drivers, we would probably have a pretty high failure rate," said David Fierro with the Nevada Department of Motor Vehicles.
A 50-question test stands between drivers and their license. Anything driving-related is fair game.
The questions for the most part are common sense; even so, answering them is difficult without studying.
"There may be some aspects of the laws and the rules that they really would not be able to answer on a test," said Fierro.
Questions like at what age it's okay to ride in the back of a pickup and how to attach a fifth-wheel to a kingpin tend to trip people up. A maximum of 10 wrong answers are allowed.
"What we are finding is they were not as prepared as they should have been," said Fierro.
In fact more than half of people don't pass the test the first time they take it.
The failure rate among authorization card applicants is 14% higher than normal applicants.
DMV officials say this actually proves the need for this law. Many of these drivers were already on the road, but they did not know all the rules.
