About two-thirds (68%) of young drivers 18 to 20 are willing to answer incoming phone calls on some, most, or all driving trips, and most continue to drive, at slightly higher rates than older drivers.
Young drivers 18 to 20 have the highest incidence of self- reported crash or near-crash experiences compared to all other age groups and the highest incidence of phone involvement at the time of the crash or near-crash.
