The driver who hit the squad car – Moises Hernandez, 44, of Blue Island – was charged with a violation of Scott’s Law, which requires drivers slow down and move over one lane for an emergency vehicle stopped at the side of the road with emergency lights flashing.

Hernandez was also charged with driving under the influence of alcohol, and was ticketed for failure to reduce speed to avoid an accident and improper lane usage.

Anyone who violates Scott’s Law faces a fine of at least $250 and up to $10,000 for a first offense. If the violation results in someone being injured, the violator’s driver’s license will be suspended to six months to two years.
