In-vehicle monitoring and feedback devices capture and report on driving performance, and are often used for novice teen drivers. Immediate in-vehicle feedback technology uses lights or sounds to alert drivers of unsafe driving, such as high g-force events caused by rapid acceleration, braking, or turning. Such devices can also capture other safety-related information, including speeding, seat belt use, or cell phone use1. Drivers can also receive reports about their driving performance via text or email, and families of novice teen drivers can review driving performance through reports, individualized summaries and tips, or video recordings2, 3. The monitoring devices can be installed by private vendors or car insurance companies, or can be built into some newer vehicles; smart phones may also be used to provide monitoring and feedback. In-vehicle monitoring and feedback is also sometimes used by businesses and insurers to monitor commercial drivers and car insurance customers1.

Evidence of Effectiveness
There is some evidence that immediate in-vehicle driving feedback for novice teen drivers, in the form of warnings or alarms and paired with delayed feedback for their families, reduces risky driving behaviors such as speeding and high g-force events (e.g., sudden acceleration, braking, and turning)2, 3, 4, 5. However, additional evidence is needed to confirm effects on driving behavior and determine effects on crash rates.
Immediate feedback paired with videos of high g-force events and driving report cards sent to families appear to reduce the frequency of g-force events2, 6, 7, while immediate feedback for drivers without reports for families may not2. Effects appear to be stronger for teen drivers with a history of higher rates of g-force events6, 7, 8; these higher-risk drivers, however, may only reduce rapid turning and acceleration during the parental monitoring period7. Such paired interventions may teach drivers to scan for and react to hazards, which may reduce abrupt braking even after in-vehicle feedback ends6, 7.
Parental monitoring, along with guidance on engaging with their teen driver’s behavior, may have stronger effects on reduction of high g-force events compared to immediate feedback to drivers only3. Receiving alert sounds for speeding or unbelted driving, combined with parental notification, may reduce such risky behaviors among teen drivers4. Teen drivers who receive in-vehicle crash alerts from manufacturer built-in features, without parental monitoring, may reduce unsignaled lane change and lateral drifts, but increase following at a close distance compared to their peers who do not receive such alerts9.
Immediate in-vehicle monitoring and feedback may also improve adults’ driving behavior; studies report decreases in risky driving among commercial vehicle drivers when combined with safe driving coaching10 and short-term effects on reduced speeding among adult drivers with speeding violations11.
Impact on Disparities
Since 2009, many car manufacturers have developed and implemented teen driving monitoring technology on select vehicles; examples of such in-vehicle systems include Ford’s MyKey, General Motors’ Teen Driver, Hyundai’s BlueLink, and Kia’s Uvo12, 13. Parents of teen drivers can also install an electronic device or a mobile app-based tracking system in their child’s car individually or via a car insurance company’s tracking device program14. The cost of monitoring devices varies by its features and services1.
