speed limiters
Maximum speed enforcers
Speed limiters are devices installed in vehicles that prevent them from exceeding a preset maximum speed.
They work by electronically restricting engine power or fuel flow once the vehicle reaches its programmed limit.
Commercial trucks and buses commonly have speed limiters as a safety requirement, and some jurisdictions mandate them for certain vehicle classes.
Parents sometimes install aftermarket speed limiters on teen drivers' cars.
The technology is distinct from cruise control, which maintains a set speed rather than capping it.
