Rolling/moving roadblocks, both with Officers in front and on both sides of the vehicle (if safe) or contacting 18-wheelers via Citizen Band radio are still used in some areas, particularly on freeways and interstates in the US, particularly in rural areas. This method, however, is becoming more uncommon.
In more urban areas, though, police units ahead of the suspect will block traffic at intersections and also deploy stingers/spike strips in an attempt to stop the suspect, if the PIT maneuver is not authorized or is unsuccessful.
