Most people know what it means when a school bus comes to halt, red lights flash, and a stop sign swings out from the driver's side.
Cars behind the bus and approaching it must stop until the sign retracts after all students either climb aboard or disembark.
At a four-way intersection, cross traffic also has to wait.
It's about children's safety; most everyone understands this and obeys Pennsylvania's School Bus Stopping Law.
Yet about 1,000 people a year are in too much of a hurry and ignore the stop signs.
They're not only reckless, but bold, considering a conviction carries a 60-day driver's license suspension, five points on their driving record, and a $250 fine
Perhaps they see there are no police officers around and figure the bus driver is too busy to jot down their license plate numbers.
What are the odds of getting caught?
If a new bill becomes law, the odds will be pretty high.
State Rep. Seth Grove, R-Dover Township, wants to give school districts the option of installing cameras on the school bus stop signs. They would sense when a car is passing and snap images of the license plates, allowing police to track down the offender and cite him or her.
We support the bill because it's optional, and -- unlike York City Police Department's license plate scanners that are constantly recording images of every license plate in the vicinity -- the cameras would only capture drivers in the process of breaking the law.
The bill already has the backing of much of York County's delegation, including House Majority Whip Stan Saylor, R-Windsor Township.
"I agree with the big brother argument on some things, but in this case there's no way a bus driver can catch a license plate number," Saylor said. "The bottom line is they're putting a young child in danger and breaking the law, and I don't know how you're supposed to catch these people.
"If somebody has a better idea than Seth has, let us have it," he said.
Don't look at us.
Short of stationing police officers at every bus stop, twice a day, we don't know what else will stop the scofflaws.
That, of course, is just not feasible.
Cameras on school buses seem to be a good option for catching these drivers and, hopefully, deterring others from such behavior.
