Most US states{\textquoteright} Graduated Driver Licensing (GDL) policies apply only to novice drivers age \<18. Four (of 51) US jurisdictions have extended GDL restrictions (nighttime, passenger) to older novice drivers; others are considering the appropriateness and feasibility of extending coverage as well.To directly inform this discussion, we conducted novel analyses in New Jersey (NJ){\textemdash}a state that applies GDL through age 20{\textemdash}and critically reviewed the evidence related to extending GDL restrictions.We analyzed a unique linked database containing the licensing and crash history of all NJ drivers to estimate monthly per-driver rates of overall, nighttime, and multiple-passenger crashes for all novice drivers (license age 17; 18{\textendash}20; 21{\textendash}24; and >=25). Additionally, we reviewed US and international literature to assess: the effect of extending GDL to cover older novices on crash rates; issues with compliance, acceptance, and enforcement; and evidence related to specific provisions.Initial crash rates of novice NJ drivers first licensed at age >=21 were substantially lower than those of novices licensed at age 17{\textendash}20; further, novices licensed at age >=21 experienced less steep crash reductions over the first year of licensure. Differences in crash reduction curves between periods covered by current NJ restrictions (11 pm{\textendash}5 am) and earlier nighttime crashes (9 pm{\textendash}11 pm) support a 9 pm starting time for nighttime restrictions for novice drivers licensed at age \<20.Collective evidence{\textemdash}including novel analyses conducted in NJ{\textemdash}suggests that drivers licensed at ages 18{\textendash}20 would benefit from GDL restrictions limiting high risk exposure. There is a lack of compelling evidence for additional GDL policies for drivers licensed at age 21{\textendash}24 and no evidence to indicate a need for drivers licensed at age >=25.}, issn = {1353-8047}, URL = {https://injuryprevention.bmj.com/content/24/Suppl_2/A92.3}, eprint = {https://injuryprevention.bmj.com/content/24/Suppl_2/A92.3.full.pdf}, journal = {Injury Prevention} }
