“The driver seemed very amped up, very agitated, very aggressive, and she thought that he was under the influence of something,” Krishna Abrams, Solano County district attorney, told Fox 6.

Schwab agreed to undergo a blood test in the jail, and the results were negative, except for caffeine.
Forensic toxicologist Edwin Smith told the news station that caffeine can actually improve the ability of most drivers.
“Very little, if any, of those people with problems in the performance in a task, such as driving,” Smith told Fox 6. “Most are probably doing it as well, and possibly even better than they would do without it.”
Abrams dropped the DUI charges against Schwab on Wednesday.
