PA SB1237

Authorizes local law enforcement officers to use RADAR for speed enforcement on local highways, and on state highways with Commonwealth agency authorization, after completing Pennsylvania State Police-approved training and operating from clearly marked, visible vehicles.

Requires municipalities to adopt an ordinance authorizing RADAR use and post at least four warning signs within 500 feet of municipal borders before local officers can use RADAR within their boundaries.

Prohibits convictions based on RADAR/LIDAR evidence unless speed exceeds the limit by 10+ mph (or 6+ mph in zones over 55 mph), except in school zones and active work zones where no threshold applies.

Caps municipal fine revenue at 101% of the prior year's speed violation fines, with excess amounts remitted to the Motor License Fund; violations based on local RADAR evidence do not count as criminal convictions or result in license points.

Mandates a 90-day written warning period after a municipality adopts its RADAR ordinance, and requires RADAR devices to be tested for accuracy annually while mechanical/electronic devices must be tested every 60 days.
