"Courts generally look to one of two theories supporting the validity of implied consent laws. According to the first theory, driving on public roads and highways is a privilege, not a right. Only those who adhere to state laws, including laws prohibiting driving while intoxicated, are entitled to the driving privilege. Under the second theory, courts consider implied consent laws to be a reasonable regulation of driving pursuant to the state's Police Power, so long as the laws do not violate due process. Courts have weighed the interests of society against the interests of individuals, and have determined that drunk or drug-impaired drivers are enough of a danger to society that a slight infringement on the liberty of individuals is justifiable." This is my understanding of "implied consent".....a D.L. suspension for refusal...then the DWI would be based on the field sobriety test... Is this a correct understanding?  thanks, Gary Crum
