Can charges for DUI be dropped before the arrainment if there is not enough evidence to prove the case? I was charged with DUI, wreakless driving and endangering another person. I had consumed some alcohol earlier in the day but was not impaired. I was driving a new car that I was not used to driving. It spun and hit a mailbox. I had a passenger .He was uninjured. I refused the breathalizer, I was booked and three hours later taken to a hospital for blood test. The Dr was so shakey, he could NOT get even one vial of blood. The police officer did not take me back to jail. He drove me home.
