2006 GMAC Insurance National Drivers Test - Methodology

GMAC Insurance conducted an online survey to test driving knowledge among the American driving population.  The study was administered by MarketTools, using the company’s proprietary ZoomPanel and zTelligence research platform. 

The survey was composed of two parts.  First, a multiple choice test simulated a standard written drivers test (not state specific).  The second part evaluated knowledge of the rules of the road as well as behavioral responses to driving situations.  Following completion of the survey, respondents were given their score on the 20 drivers test questions.

The sample was comprised of 5,288 total respondents.  Inclusion criteria required licensed drivers aged 16-60+.  The sample was balanced of males and females and to the latest Census quotas for individuals.  Furthermore, it included at least 100 respondents from each of the 50 states and the District of Columbia. 

Analysis was conducted across age groups, gender, ethnicities and state/geographical regions.
