Collision technology now available on Mack Trucks

The technology uses four sensors that alert a driver when objects, pedestrians, cyclists or motorcyclists are in the truck’s blind spot.


Mack Trucks, Greensboro, North Carolina, has announced Attleboro, Massachusetts-based Sensata Technologies’ PreView multisensor collision warning system is now available on the Mack LR, Mack LR Electric and Mack TerraPro models.   

According to a news release, Sensata uses four radar sensors, one on the front, rear and both sides of the vehicle. The radar detects objects, pedestrians, cyclists and motorcyclists, called vulnerable road users (VRU) in a driver’s blind spot.   

“Mack Trucks is committed to safety, and the PreView safety system will help mitigate the risk of accidents for drivers and improve the safety of those on the roadway with heavy-duty vehicles,” says Josh Seiferth, Mack Trucks cabover product manager. “Ninety-five percent of refuse collection occurs in an urban or suburban setting, such as neighborhoods, schools, apartment complexes and more. Mack is proud to be one of the first refuse vehicle OEMs (original equipment manufacturers) to utilize a system to help detect VRUs.”  

When a VRU is detected, an audible alert is sounded, and the A-pillar lights flash, alerting drivers there is an object or VRU in a blind spot. The PreView radar system is available as an option and is factory-installed on new builds. Customers may also retrofit their trucks with the system by contacting their local Mack dealer.  

Mack says PreView is always on. The system requires no maintenance unless something damages it or a software upgrade is available.  

The Mack LR is a diesel-powered low-entry refuse vehicle featuring large windshields, side windows and a rear wraparound window for improved safety. The Mack LR Electric, Mack’s first fully electric Class 8 vehicle, also features the same visibility enhancements.  

The Mack TerraPro model features the forward-most window glass in the industry to help keep others on the road and job site safe. Along with refuse, the TerraPro model also is available as a concrete pumper and conveyor belt configuration.
