How does a truck’s “black box” or EDR help in an accident case?

An Event Data Recorder (EDR) captures critical data in the moments leading up to and during a collision. It can show the truck’s speed, whether the brakes were applied, the engine’s RPM, and other key information. This data provides an unbiased account of the truck’s operation and can be crucial evidence to prove a driver was speeding or failed to brake in time.
