Traffic cameras can catch drivers blowing through stop signs and blocking the box, among other things.
Police in D.C. are extending the warning period for more than 100 new traffic safety cameras before issuing real tickets to violators.
Drivers caught by the 132 new traffic cams were supposed to start receiving tickets today, but the Metropolitan Police Department has decided to extend the warning period to an undetermined date.
"Warning tickets will continue to be issued until every location has 30 days of tickets," said Gwendolyn Crump, an MPD spokeswoman. "We are working to ensure that all possible warning tickets are mailed prior to issuing live tickets."
John Townsend at AAA Mid-Atlantic says the MPD is doing right by drivers.
"This is designed to make sure that motorists are aware they have incurred tickets," he says.
The cameras are designed to catch drivers who run stop signs, violate crosswalks and speed through intersections, among other violations. D.C is the first city in the country to use them.
Crump says the department is working to ensure that all possible warning tickets are mailed prior to issuing live tickets.
