Abstract

Purpose: Teen drivers are at high risk for motor vehicle crash injury. Previous research has shown that risk-based injury prevention programs for subpopulations or individuals can be successful as build-outs to universal strategies. The goal here was to assess the efficacy of state agency-administered parent advisory letters as a supplement to graduated driving license and seat belt policies.

Methods: A multiple-method approach was used to collect information about parents’ reactions and actions after receiving the letter. A mail survey, comprised of closed- and open-ended questions, was administered to gather information. The survey resulted in 309 parent responses which was near the expected 10% response rate, resulting in robust statistical analysis. Statistical analysis of the closed-ended responses was complemented by thematic analysis of the open-ended parent responses.

Main Findings: The parent advisory letter was successful in initiating parent engagement with teen drivers. The letter was generally viewed as positive. About 80% of parents reported action after receiving the letter such as discussions with their teen, learning more about teen driver risk, and finding additional driver training. Comments and an open-ended question provided insight for program refinement. For instance, some negative comments were associated with parents’ perception the letter was accusatory or overreaching. Others commended the letter, saying it provided additional knowledge and suggestions that were helpful.

Application: It is an example of continued innovation to improve public safety. Results inform other states considering low-cost individualized programs to complement their ‘one-fits-all’ driver improvement strategies.

Novelty: Parents are highly influential with teens. An advisory letter to parents of teens with high motor vehicle crash risk elicited engagement. Many parents reported action spurred by the advisory letter such as discussions with their teen, learning more about teen driver risk, and finding additional driver training.
