I don't know if 1st year accident rate is available but overall teen accident rate is. Here is a copy. This is from the Insurance Information Association. Motor vehicle crashes are the leading cause of death for teenagers. 16 year-olds have higher crash rates than drivers of any other age. 16-year-olds are three times more likely to die in a motor vehicle crash than the average of all drivers. 3,490 drivers age 15-20 died in car crashes in 2006, up slightly from 2005. Drivers age 15-20 accounted for 12.9 percent of all the drivers involved in fatal crashes and 16 percent of all the drivers involved in police-reported crashes in 2006.
