Whether your vehicle was weaving over the yellow line or you had a tail light out, a California officer had to have a reason to pull you over. Once you are on the side of the road, if you do anything that causes suspicion that you may be intoxicated, he or she could decide to give you a test. We at Edward Y. Lee, attorney at law, are aware of all the nuances of this test, and when the results may not be admissible against you.
According to AAA, the National Highway Traffic Safety Administration has developed a battery of three roadside tests that officers must be trained to perform correctly. The officer must first ask you if you have any medical conditions that would interfere with the outcome of the test.
