Safety functions for risk prediction

Safe driving is easier if the truck can predict potential dangers and warn the driver as quickly as possible. To do this, the Quon includes advanced safety systems such as the Traffic Eye Brake System and the Lane Depature Warning System (LDWS) as standard.

The goal of "safety that puts people first" mandates safe conditions for drivers as well as those in the surrounding environment. Safety is built into all basic features, with heat-dissipating, fade-resistant disc brakes standard on all models.

Active safety: risk prediction for driver safety

Traffic Eye brake system

Dual monitoring with millimeter-wave radar and camera dramatically improves detection of the vehicle ahead. If the truck continues to close on the vehicle ahead, the system applies the brakes automatically to slow the truck and prevent the collision.

Traffic Eye Brake System components

  1. Camera - Functions as a sub-sensor when detecting stopped vehicles.
  2. Millimeter-wave radar - Functions as the main sensor when detecting the vehicle ahead.

Traffic Eye Brake System operation figure

  1. Uses both millimeter-wave radar and camera to monitor conditions in front of the truck.
  2. While driving, if the system detects a chance of collision with the vehicle ahead, it sounds an alarm and displays a warning indicator to alert the driver.
  3. If the vehicle gets close enough for a collision to be possible, the system quickly applies the brakes to reduce the potential damage from a collision.

Note: the Traffic Eye Brake System provides assistance for safe driving. However, it does not guarantee that all collisions will be avoided. It might not be possible to use this system in some road, vehicle, and weather conditions. Please take care to drive safely without relying on this system.

UD Trucks All-New Quon Lane departure warning system

Lane departure warning system

The cab camera detects the traffic lanes to the left and right. If the driver unintentionally leaves the lane at speeds of 60 km/h or more, an alarm sounds and an indicator flashes. Note: this function is not triggered by the brakes or turn indicators.

UD Trucks All-Nre Quon Driver Alert System

Driver alert system (optional)

The camera installed inside the cab recognises the positional relationships between traffic lanes and vehicles, and estimates driver awareness based on steering irregularities. If the driver's concentration drops, a two-step alarm and warning message on the multi-display alert the driver and suggest a break.

UDSC (UD Stability Control)

If the UDSC sensor detects conditions in which the truck could become unstable, such as curves or slippery road surfaces, the system applies control appropriate to engine output and braking power to each tire to maintain stability. UDSC is available on all models.

  1. Drifting (snowy and muddy roads, etc.)
  2. Sliding/Spinning
  3. Rollover

Basic safety: ensuring safe driving by reducing driver fatigue

UD Trucks All-New Quon headlamp

LED headlamps

Long-lasting LED low-beam lamps provide bright, clear light to improve night visibility for safe driving.


Disc brakes

Disc brakes with high heat dissipation and superior fade resistance provide reliable braking performance. In addition, because they are less susceptible to water penetration, they provide stable braking performance even in adverse conditions. They respond quickly and smoothly to the operation of the brake pedal and reduce the impact of braking.

UD EEB (UD Extra Engine Braking)

The UD EEB function on the GH11 engine maintains a high engine rpm to ensure maximum auxiliary braking performance.

Safe brake blending

Brake blending provides superior braking efficiency and optimal balance between the main brakes and auxiliary brakes, simply by pressing the brake pedal.

Immobiliser, equipped as standard

The immobilizer is equipped as standard on all models. The engine can be started only with the dedicated key, helping to greatly reduce the risk of vehicle theft.
