BETHLEHEM, Pa. – Roving construction crews – the kind you see blacktopping a road, painting lines, inspecting a bridge or installing a traffic signal – are often protected from oncoming traffic by a specialized truck outfitted with a crash barrier.
The crash trucks, fitted with a device called a truck-mounted attenuator, have been credited with saving lives. But the workers who drive them are inevitably placed in harm’s way.
On Monday, a Pennsylvania company demonstrated a new driverless crash truck that it hopes will improve safety at work zones around the country. Two of the vehicles will make their debut at highway construction sites in Florida by the end of the year under a state Department of Transportation pilot program.
