Florida Highway Patrol investigators say drivers need to follow the "Move Over" law, in order to prevent deadly accidents, similar to those that killed four people this weekend.
FHP Trooper Chelsea Richard, tow truck driver John Duggan and driver George Phillips were all killed on Saturday when a car lost control on a rain-slicked Interstate 75 in Marion County and plowed into them on the side of the road.
In Orange County, Marcceus Marc, a father of seven, was killed when another driver lost control in the rain and crashed into him as he helped another driver who had just crashed.
"We want drivers to realize there is a very dangerous risk when you get out of your car to help somebody," said FHP Trooper Kim Montes.
She said very few drivers follow the Move Over law, which stipulates drivers must move over one lane of traffic away from any emergency crews, tow truck or disabled vehicle on the shoulder of the road.
If that is not possible, drivers must slow down to 20 mph under the posted speed limit, Montes said.
"You can't be sorry after the fact," she said. "You have to be able to prevent these crashes."
Local 6 watched as several drivers on Interstate 4 in Seminole and Orange counties drove full speed passed several accidents on Monday.
In one case, a Road Ranger had a flashing arrow telling drivers to change lanes, and they all ignored the signal.
"If you hit and kill someone on the side of the road that's been simply to help someone in need, you have to live with that for the rest of your life," Montes said.
