A motorist on Interstate 75 in Hillsborough County slammed on her vehicle's brakes and stopped, causing a crash, then drove off, blew a tire and overturned Thursday, troopers say.

  • Melanie Zawacki of Michigan faces multiple charges
  • FHP says she stopped on I-75, causing crash, then drove for 2 miles
  • Troopers say alcohol was a factor in Zawacki's crashes

Melanie Zawacki, 27, of Cadillac, Michigan was driving a 2003 Pontiac Montana southbound at about 5:30 p.m. near the Waters exit when she stopped "for no apparent reason" in the outside center lane of I-75, a Florida Highway Patrol report said.

The driver of the vehicle behind her was unable to avoid Zawacki's vehicle and rear-ended it.

Zawacki continued southbound on I-75 for two more miles, troopers said, until the Montana's right rear tire blew out. It left the roadway, rotated and overturned, FHP said.

Zawacki and her 27-year-old passenger, also of Cadillac, were unhurt in the rear-end collision but sustained minor injuries in the second crash.

The occupants of the 2013 Dodge pickup that rear-ended Zawacki's Montana on I-75 — a 42-year-old man and a 13-year-old girl, both of Wesley Chapel — were unhurt.

All were wearing seat belts.

The FHP report said alcohol was a factor in Zawacki's crashes. She faces multiple charges.
