    Large vehicles like buses and big rig trucks are just as much of a safety concern as everyday cars, and US regulators think technology might be the key to saving lives. The NHTSA and FMCS have proposed installing speed-limiting devices on big commercial vehicles (those with a weight rating over 26,000lbs) to both reduce the chances of a crash and minimize damage when an accident happens. It could help with fuel efficiency and durability, too, by discouraging lead-footed drivers.
