FDOT installed a speed limit sign to stop reckless driving. A driver ran into it.

Residents who live along Northwest 135th Street say they started calling for stricter speeding prevention after a car veered off the road in April and killed the driver.

Since that crash, FDOT says it installed a speed limit sign here in May, 

CBS News Miami has learned that two more crashes have happened since then, including one this past week, where a car knocked over this new speed limit sign.

This is the third crash Carlos Tapanes' house cameras have captured outside his house in the last five months. Now, drivers may not see the downed 40 mph speed limit sign that was installed four months ago.

"It's like a big 'Hell to you, Hell to your speed sign,'" Tapanes said.

FDOT said it manages this road. Tapanes has been pleading for the state to do something to stop the speeding. In the meantime, he worries that every loud engine he hears could be the next crash.

"Nothing has changed. Tires are still squeaking," Tapanes said. "Speeding is still going on. Running off the road is still going on."

Tapanes said he will continue advocating for safer streets, but he also noted his neighbors have just accepted crashes as a part of life here. 

"They just have given up. They just said, you know, leave it alone and whatever happens, happens," Tapanes said.

Tapanes said this downed sign is itself a sign that stricter measures are needed, such as speed bumps and traffic lights. 

"It gets them off the hook. 'Oh, look, we put up signs.' Cause last time there wasn't a sign. But someone hit the sign, and now it's on the floor," Tapanes said.

CBS News Miami has sent a photo of this damaged sign over to FDOT to see if they'll come and fix it. An FDOT spokesperson said they'll have to look into whether other measures, such as speed bumps, are possible here.
