COLUMBUS, Ohio -- Dozens of people gathered Sunday night to remember a local teenager who died in a car wreck one year ago, NewsChannel5 reported.

Michelle Sanderbeck died when the car she was riding in flipped over. Her death has caused her parents, Ray and Debbie Sanderbeck, to go on a crusade to change the laws.

In March 2006, Michelle and four friends were traveling on East Smith Road after a trip for ice cream. The driver, a 16-year-old who'd had his license for only three weeks, took a sharp S-curve at more than 70 mph.

The car flipped and slammed into a stone wall. Michelle, a sophomore at Medina High School, was killed. She was 15.

Since the accident, the Sanderbecks have been working to toughen Ohio's driver's license law and establish more and better driver's education programs at the state's high schools. And after almost a year of work, their efforts have paid off.

Former Gov. Bob Taft signed into law a bill that puts more restrictions on teenage drivers, limiting the number of passengers and the times they are allowed on the road.

The Sanderbecks have been on a relentess crusade to change laws for teen drivers.

The law takes effect next month, and it prohibits drivers under 17 from having more than one non-family passenger.

Those drivers also can't be on the road between midnight and 6 a.m.

According to data from the Ohio Department of Public Safety, 246 drivers between the ages of 16 and 20 died in traffic accidents in 2005 -- the highest number out of all age groups recorded. Among drivers ages 21 to 25, there were 222 fatalities, the data show.
