The state wants you to pay attention to traffic control devices that warn of of hazardous conditions.
And if a barricade is up, they don't want you to ignore it.
If you do, you could receive two points on your license.
Rep. Todd Stephens (R-151) sponsored House Bill 2199, also dubbed "Turn Around, Don't Drown," primarily to protect first responders.
"This is a major victory for our police and emergency workers who place their lives on the line to rescue drivers who ignore temporary barricades and become trapped in flood waters," Stephens said in a statement. "This has become a growing problem that must be addressed."
The measure received unanimous consent in both houses with local representative Kathy Rapp (R-65), as well as state senators Joe Scarnati (R-21) and Mary Jo White (R-25) voting in the affirmative.
The charge, a summary offense, enacts a fine of up to $250 for anyone who is caught disregarding such barricades and tacks on an additional maximum fine of $250 if someone ignores a device and requires emergency assistance as a result.
The bill passed the Pa. House of Representatives on June 29 and the Senate on June 30.
It will take effect in 60 days.
Governor Tom Corbett gave the measure his signature of approval on July 5.
