I was pulled over by a cop I had a 2-3 drinks that night ( i had just graduated from college) long story short the officer asked if I was drinking and asked me to do some field sobriety tests. He did not give me any other tests no breath test, no blood, and no urine test. After some time he asked if i had someone to pick me up or go to jail. He was very serious but he saw i just graduated. My friends picked me and my car up and that was it. can i still be charged for anything if the cop thought i was impaired but no chemical tests were done? or am i just lucky he let me go?
