A new enforcement initiative to save lives was launched this week by the City of San Antonio. They call it “Don’t Block the Box.”

It's part of an ongoing campaign to reduce the number of pedestrian deaths and serious injuries in the city.

“The Box” refers to the part of an intersection that includes the crosswalks. "Blocking the box" means that a vehicle has blocked other people from driving, walking or biking across the road.

Throughout the month of May, San Antonio police will be doing targeted enforcement during rush hour all across town.

The state law prohibiting blocking an intersection has been on the books for years, but this stepped-up enforcement campaign by the city is new.

Signs reminding drivers about the rules went up in January but this week, SAPD started issuing tickets to drivers.

The citations carry a fine of $200.

The effort is part of the city's "Vision Zero" initiative that hopes to eliminate all pedestrian fatalities and serious injuries. The pilot program runs through May.

A preliminary report on what the engineers have learned so far will be presented to the City Council Public Safety Committee on May 17.

Here is the full list of intersections included in the pilot program, one for each City Council district:

District 1: Euclid at San Pedro
District 2: Houston at W.W. White
District 3: Logwood at S.W. Military
District 4: Springvale at Valley-Hi
District 5: Commerce at Zarzamora
District 6: Culebra at Westwood Loop
District 7: Fredericksburg at Woodlake
District 8: Huebner at Fredericksburg
District 9: Silversands at West
District 10: Bulverde at Autry Pond – Classen Rd
