The strips are not a technological quick fix for sleepy drivers. An impediment to diagnosis is a lack of physician education on the recognition of circadian patterns in order to sleep during the day (Kessler, 1992). Some evidence exists that napping before a long A recent synthesis of reports on the effectiveness of rumble strips shows hours of sleep per 24 hours as compared with day workers.
