Potential benefits of restrictions on the transport of teenage passengers by 16 and 17 year old drivers

Abstract
Objectives—The presence of passengers is associated with fatal motor vehicle crashes of teenage drivers. A restriction against newly licensed teenage drivers carrying passengers has been included in some, but not all, graduated licensing systems. The purpose of this study was to predict the net effects on all types of road users, including vehicle occupants and non-occupants, of possible prohibitions against 16–17 year old drivers carrying passengers.
