Blind spot sensors are a common safety feature in commercial vehicles because they significantly enhance the driver's awareness of their surroundings. These sensors are designed to detect vehicles in the blind spots on either side of the truck, which is particularly important given the size and length of commercial vehicles. When another vehicle enters a blind spot, the sensors provide visual or auditory alerts to the driver, helping to prevent potential collisions during lane changes or turns.

This feature is critical for maintaining safety on the road, as commercial vehicles often operate in heavy traffic and complex driving environments. By utilizing blind spot sensors, drivers can make safer maneuvering decisions, ultimately leading to fewer accidents and improved overall safety for everyone on the road.

In contrast, automatic windscreen wipers, while a convenience feature, do not directly enhance safety in the same way. Leather seats for comfort and sunroofs are primarily comfort-oriented additions that do not contribute to the vehicle's safety systems.
