Japanese truck maker Mitsubishi Fuso Truck and Bus has unveiled a heavy duty model with a device to remove drivers' blind spots.
The new truck has sensors on both the front and passenger side of the vehicle.
If there are cyclists or pedestrians nearby when the driver activates the turn signal or begins turning, an alarm will sound. If the system thinks a collision is imminent, it will trigger the brakes for an emergency stop.
The transport ministry says it's the first time trucks with this feature have gone on sale in Japan.
The Japan Trucking Association says there were 51 fatal accidents last year involving a truck hitting pedestrians at an intersection. More than a third of them occurred when the vehicle was making a left turn.
