The safest and most advanced truck we've ever built.
BEST-IN-CLASS SAFETY
Introducing Detroit Assurance
Technology gets tough in the 49X, the first Western Star to feature the most advanced suite of active safety systems ever offered to the vocational market — Detroit Assurance®. But it not only helps keep people safe, it helps you reduce the repair and operational costs of having a truck out of service by avoiding collisions — which can mean game-changing productivity to you.
SIDE GUARD ASSIST
A game changer for safety in and around busy jobsites, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator.
Active Brake Assist 5
Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if braking is necessary. It's the only system on the market that works down to 5 MPH*, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck's path, alerting the operator while partially braking, followed by full braking if the operator does not react.
* with DT12 Transmission
Adaptive Cruise Control to 0 MPH and Tailgate Warning
Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH* and Tailgate Warning to ease driving in stop and go traffic, as well as help mitigate front and rear collisions as operators travel from one jobsite to the next.
Brake Hold Mode
Available in 2022, Brake Hold Mode enhances driver safety and comfort on the road and at the jobsite. This state-of-the-art feature keeps a truck* stopped when the driver removes their foot from the brake pedal, or if their foot unintentionally slips off.
