School zone speed cameras are common for safety, operating specific hours with varied penalties, from civil fines to automatic double charges.
Speed cameras use radar, lidar, or ANPR to measure your speed; radar uses radio waves, lidar uses light pulses, and ANPR calculates average speed over distance.
Drivers face varying speed camera enforcement thresholds and margins of error across countries, from strict no-tolerance policies to allowances based on percentages or fixed values.

Average speed cameras use ANPR to time vehicles between two points, calculating speed over a distance to deter continuous speeding.
