Ever since four beach visitors were struck by cars on Volusia County Beaches in 2010, lifeguards have been trying to get drivers to slow down.

Volusia County's Beach Safety and Ocean Rescue has a new tool to try to get drivers to slow down on the beach. And it’s something that drivers are more accustomed to seeing out on the highway.

Beach safety managers say they have been using the speed signs for about a month now, and they've deployed two of those signs in high-traffic areas.

"It has radar and it shows how fast oncoming traffic is coming towards the sign," said Captain Ray Manchester, Volusia Beach Safety and Ocean Rescue.

In 2010, four beach visitors were struck by cars, and one of those struck was a child who was killed.

Since then, the county has taken several measures to protect beach visitors, including reducing the speed limit to 10 miles per hour.

"If they go over 10 miles an hour, it starts flashing if their speed is over 10, and then it eventually shows a slow-down sign; and it seems to be very effective," added Capt. Manchester.

Beachgoer Parker James drove past this sign -- the flashing numbers quickly reminded him about the speed limit.

"Red flags pop up ... you know you've got such an amount of people out here, you can't be driving fast or somebody is gonna get hurt," said James.

Capt. Manchester says drivers are slowing down because of this sign,  and the agency has even issued a few citations.

The cost of the signs is about $4,000 which the county paid for using money collected from previous citations issued by beach safety officers.

Captain Manchester says the county could get more of these speed signs when they're needed.

The second deployed speed sign is located in New Smyrna Beach near the Flagler Avenue approach.
