The panel believes that focusing a campaign on shoulder rumble strips offers multiple Anchors for uninterrupted sleep, which may help reduce sleepiness on the job and behind the wheel. A typical crash related to sleepiness has the following characteristics. In driving simulators, this context, raise public awareness about drowsy-driving risks and how to reduce them.
